- 2. PHYSICAL PROPERTIES OF MATTER Physical properties of matter include properties that do not change the chemical nature of materials. Some properties crop easily be observed using your five senses, while others require testing or experiment to identity.
- 4. Some examples of the physical properties of matter are color, height, volume. malleability (ability to bend), texture, freezing point, boiling point, magnetism, density, opacity, and others.
- 5. LOOK AT THE PICTURES BELOW. CAN YOU IDENTIFY THE PHYSICAL PROPERTIES OF THE OBJECTS OR MATERIALS SHOWN IN EACH OF THEM?
- 6. The physical properties of matter can be further classified as either extensive or intensive.
- 7. EXTENSIVE PROPERTY OF MATTER Extensive properties of matter are physical properties that depend on the amount of matter present. For instance, the volume of water inside a full container depends on how big the container is.
- 8. THE FOLLOWING ARE SOME OF THE EXTENSIVE PROPERTIES OF MATTER. TO DETERMINE EACH PROPERTY, YOU CAN ASK YOURSELF THESE QUESTIONS? Height - How tall is the object? Length - How far are the opposing sides of the object from each other?
- 9. Mass - How much amount of matter is present in the object? Volume - How much space is taken up by the substance? Amount of energy - How much energy is needed to do work?
- 10. Extensive physical properties of matter can be measured using different measuring tools. For example, the mass of an object can be measured using a weighing scale. The length of an object can be measured using a ruler. The volume of a liquid substance can be measured using a volumetric flask or a graduated cylinder.
- 11. INTENSIVE PROPERTY OF MATTER Intensive properties of matter are properties that do not depend on the amount of matter present. For instance, the color of a black cardboard will not change even if you cut or fold it into two.
- 12. THE FOLLOWING ARE SOME OF THE INTENSIVE PROPERTIES OF MATTER. TO DETERMINE EACH PROPERTY, YOU CAN ASK YOURSELF THESE QUESTIONS. 1. Color - What color/s make/s up the appearance of the matter? 2. Density - Given the constant volume, how heavy is the substance? 3. Malleability - Can it be bent easily?
- 13. 4. Magnetism - Is the matter attracted to magnets? 5. Texture Does the appearance of the matter look rough? How does it feel when you touch it. 6. Opacity - Is the matter opaque? Can light easily pass through it?
- 14. 7. Freezing point - At what temperature does the liquid matter turn into solid as it cools down? 8. Boiling point - At what temperature does the liquid substance turn into vapor or gas? 9. Melting point - At what temperature does the solid material turn into liquid? 10. Ability to conduct electricity - Does the object allow the transfer of electrical current through solid or liquid?
