This document summarizes a physical experiment on the effects of atmospheric pressure on an empty soda can. The experiment involves boiling water inside an empty soda can on a hot plate, then quickly inverting the can into a dish of ice water. This causes the steam inside to rapidly condense, reducing the pressure inside the can. With the outside air pressure now greater than the pressure inside, the soda can collapses inward. The conclusions are that changes in the physical state of the water and differences in air pressure inside and outside the can cause it to collapse when exposed to cold water after steaming.

Condensation is when a gas turns into a liquid, evaporation is when a liquid turns into a gas, melting is when a solid turns into a liquid, solidification is when a liquid turns into a solid, sublimation is when a solid turns directly into a gas, and deposition is when a gas turns directly into a solid. Physical changes like melting, freezing, evaporating and condensing can be reversed, but chemical changes like rusting or boiling an egg cannot be reversed. When water freezes, it releases heat, and when an ice cube melts, it absorbs heat, meaning changes of state involve heat absorption or release.Air experiments navs catalonia

This document presents summaries of 3 experiments on the properties of air conducted by students at Sant Josep school in Barcelona, Spain. The first experiment shows that hot air expands and cold air contracts by placing a balloon-topped bottle in hot and cold water. The second experiment demonstrates that air takes up space by trying to submerge a ping pong ball in a jar with and without tissues. The third experiment illustrates that air pressure can crush an empty soda can by boiling water inside the sealed can and then quickly submerging it in cold water.Austrian presentation for air

This document provides instructions for three experiments to teach young students about air and air pollution:
1) An experiment where burning paper in a sealed jar with ice on the lid creates "artificial smog" to illustrate its appearance.
2) An experiment comparing burning paper in jars with a hot iron held above one jar and a cold iron above the other to demonstrate temperature inversion conditions trapping pollution near the ground.
3) An experiment using limewater, a syringe, and straw to test exhaled air for carbon dioxide and show how inhaled and exhaled air differ in composition.Sublimation by Waqas Siddiqe 
Sublimation by Waqas Siddiqe waqassiddiqe

Sublimation is the direct change of a substance from the solid to the gas phase without passing through the liquid phase. It is an endothermic process that occurs below the triple point of a substance. During sublimation, heat provides energy for molecules to overcome attractive forces and escape as a gas. Sublimation is used to purify solids by heating them under reduced pressure so the pure substance condenses away from any non-volatile residues. It has applications in fields like pharmaceuticals, fingerprint detection, and producing special effects.Condensation
CondensationGarden Gate Elementary
油
The water droplets that formed on the outside of the cup came from water vapor in the air condensing. When water vapor touches a cooler surface, it changes from a gas to a liquid through the process of condensation. The ice water made the cup cool enough for the water vapor in the air to condense onto its surface. Similarly, frost forms when water vapor in the air condenses onto a surface that is below the freezing point of water and freezes solid.Physical change review

To study for a science quiz, it is important to understand different types of science questions like knowledge, comprehension, analysis and synthesis. Key concepts to review include physical and chemical changes, states of matter, phase changes, and temperature-time graphs. Physical changes like boiling, melting, freezing and evaporation involve a change of state without a new substance forming. A pressure cooker allows food to cook faster by trapping steam and raising the boiling point of water inside.Can Crusher
Can CrusherCBSD - 7th Grade Science

The document describes how heating water in a sealed can causes the water particles to turn to gas, spreading out and lowering the pressure inside the can. When the can is submerged in water, the gas particles rapidly condense back to liquid, further reducing the internal pressure. This allows the higher external water pressure to crush the can as there is now more pressure outside than inside.Hot Ice
Hot IceDanaGrant
油
The document describes an experiment to create "hot ice" using sodium acetate and water. Sodium acetate is dissolved in water to make a saturated solution, which is then supercooled without freezing by preventing nucleation. When a nucleation point is introduced, the supercooled solution undergoes an exothermic phase change and freezes, releasing heat and creating a substance that feels warm despite being frozen solid. The document provides instructions for safely conducting this experiment in the classroom to observe this unusual physical phenomenon.Experiments with water

This document summarizes a series of experiments conducted by students to learn about the properties of water. The experiments demonstrated that: 1) Water vapor condenses from the air onto cold surfaces; 2) Some materials are absorbent while others are waterproof; 3) Liquid water evaporates into water vapor; 4) Salt lowers the freezing point of water; 5) Hot water is less dense and floats above cold water; 6) Salty water is denser than fresh water; and 7) Adding soap decreases the surface tension of water, allowing for giant bubbles to form. The students found water to be an amazing substance and look forward to continuing their investigation with partners from other schools.Air Pressure Activity

The document describes an investigation to determine where water goes when something dries. Students placed wet paper towels in open and closed cups to observe the drying process. They found that the paper towel in the open cup dried out as the water evaporated into the surrounding air. However, the towel in the closed cup remained wet since the water could not escape and evaporate. Evaporation is the process where liquid water changes into an invisible water vapor gas.separation of mixture.

The document discusses freezing point, which is the temperature at which a liquid becomes a solid. The freezing point depends on factors like purity and pressure. The freezing point of water is 0属C and of liquid nitrogen is -209.89属C. Freezing occurs when water molecules stick together to form ice crystals in clouds. Researchers found that some single-celled organisms can survive below -20属C by vitrifying when ice forms rather than freezing internally. More complex organisms can survive at lower temperatures by controlling the fluid around their cells. The main factors affecting freezing point are temperature, intermolecular forces, impurities, and pressure.

Sure! Here's a simple and engaging activity demonstrating high and low air pressure using the materials you listed:
**Title: Exploring High and Low Air Pressure**
**Objective:**
Students will observe and understand the concept of high and low air pressure by creating a simple experiment using everyday materials.
**Materials:**
- Red food dye
- Blue food dye
- Hot water
- Cold water
- Clear cups (at least two per group)
- Stirring sticks or spoons
- Marker or labels (optional)
**Procedure:**
1. **Preparation:**
- Fill one clear cup with hot water and another with cold water.
- Add a few drops of red food dye to the hot water cup and a few drops of blue food dye to the cold water cup. Stir each cup to evenly distribute the dye.
- Label or mark the cups if desired to indicate which is hot and which is cold.
2. **Introduction:**
- Begin by discussing with students the concept of air pressure. Explain that air pressure is the force exerted by the weight of air molecules in the atmosphere. Higher pressure means more air molecules pushing down, while lower pressure means fewer air molecules exerting force.
3. **Demonstration:**
- Pour the hot water into one clear cup and the cold water into another clear cup simultaneously. Encourage students to observe any differences they notice as the water is poured.
- Ask students what they observe. They may notice that the red water (hot) pours more quickly and spreads out more rapidly, while the blue water (cold) pours slower and stays more contained.
4. **Discussion:**
- Lead a discussion on the observations made by the students. Guide them to understand that the hot water represents low air pressure and the cold water represents high air pressure.
- Explain that in the atmosphere, warm air rises because it is less dense (lower pressure) and cold air sinks because it is denser (higher pressure). This movement of air creates weather patterns and influences our daily weather.
5. **Extension Activity (Optional):**
- Encourage students to further explore the effects of temperature on air pressure by experimenting with different temperatures of water and observing how it affects the movement of the dye.
- Students can also predict and test what would happen if they gently blew across the surface of the water in each cup.
**Conclusion:**
Summarize the key points of the activity, reinforcing the concepts of high and low air pressure and their effects on weather patterns. Encourage students to continue exploring the world around them and how science helps us understand it better.
**Safety Note:**
Ensure students handle hot water with caution to avoid burns. Assist younger students as needed during the experiment.Keynote (Science Experiment)

- 1. Soda can collapse Physical experiment from class 8尊B 2016-2017
- 2. Objective Lets study the effects of atmospheric pressure on the surface of a empty soda can!
- 3. Material 1 1 Circular glass dish 2 1 hot plate 3 1 beaker tongue 4 1 Empty soda can 5 Water 6 Ice 7 Squeeze bottle lab
- 5. Put ice in a circular glass dish with water; Put a little water in an empty soda can; Place the can on a hot plate; When steam starts off, grab the can with tongs; Quickly turn opening into the cold water; Observe what happens. Procedure
- 6. Discuss and debate Debate ideas with your colleagues, share your thoughts and analyze what happened, looking up information.
- 7. A change in the physical state of the water occurs inside of the can: it goes from liquid to vapor. When the can is placed in contact with the cold water that cools the steam, the watervapor rapidly passes to the liquid state. As the air pressure outside the can is higher than the pressure inside, the can surface collapses. Conclusions
- 8. The atmospheric air contains water vapor, oxygen, nitrogen, carbon dioxide and other gases, and their pressure is greater than the water vapor pressure inside the can. The steam condenses rapidly, comes to occupy a smaller space, so that the effect of the collapse is more intense. Conclusions
