This document discusses the four states of matter: solids, liquids, gases, and plasma. It describes the key properties of each state, including how tightly or loosely packed the particles are and their relative energy levels. Solids have a fixed shape and volume, while liquids take the shape of their container. Gases spread out evenly and have higher energy particles than liquids. Plasma has electrically charged particles and the highest energy. The document explains that adding or removing energy can change the state of matter as it causes particles to speed up or slow down. For example, adding energy to solids causes them to melt into liquids, and adding more energy turns liquids into gases.
Matter in our surroundings
- 1. Matter in our surroundings
- 2. Matter Its what the worlds made of
- 3. What do you know about Matter Solids Liquids Gases Plasma
- 4. Solids 1.Solids hold their own shape. 2.Solids have weight. 3.Solids take up space.
- 5. Liquids 1. Liquids take the shape of their container . 2. Liquids have weight . 3. Liquids take up space .
- 6. Gases 1.Gases spread out to fill the entire space. 2.Gases have weight. 3.Gases take up space.
- 7. Plasma 1.Lightning is a plasma. 2.Used in fluorescent light bulbs and neon lights. 3.Plasma is not like a gas, but the particles are electrically charged.
- 8. States of Matter What would it take for matter to move from one state to another
- 9. Energy determines the state!
- 10. Particles in solids Are packed tightly together. Have very little energy.
- 11. Particles in Liquids: Are loosely packed Have medium energy levels
- 12. Particles in Gases: Move freely Have lots of energy
- 13. Particles in Plasma: Are electrically charged Have extremely high energy levels
- 14. Mixtures may be in different phases Solid? Liquid? Gas? Plasma?
- 15. Add or subtract energy. . . When energy is added, particles move faster! When energy is taken away, particles move slower!
- 16. What will happen? Why?
- 17. So l i d + En e r g y = ? Wh e n e n e r g y i s a d d e d t o s o l i d s , t h e y b e c o me l i q u i d s !
- 18. Liquid + Energy = ? When energy is added to liquids, they become gases!
- 19. Changing States There are several names for matter changing states: State Change Phase Change Physical Change
- 20. So, did we get something new? Ice Cream and melted Ice? Chocolate and melted Chocolate? Ice, Water and Water Vapor? Steel and molten steel?
