Extra Credit Draw the particle configuration of solids (1 pt.), liquids (1 pt.) and gases (1 pt.). Make sure you label which is which.

3 Name: Date: Period: 10. Which is a property of all solids? E. Particles are far apart. F. Particles vibrate in all directions. G. Volume and shape can easily change. H. Weak forces exist between particles. Properties of Matter Quiz (Answers & Explanations) A. Gas particles are far apart. B. The forces between particles in a solid are very strong, so they don t move, but they do vibrate. C. Volume and shape easily changing are properties of gases. D. Weak forces exist between gas and, to a lesser extent, liquid particles 11. Which characteristic is a chemical property? E. Highly flammable F. Mass of 15kg G. Woolly texture H. Golden color A. Flammability, or the ability of a substance to catch fire, changes the substance into a new one. B. Mass is physical property. C. Texture is a physical description. D. Color is a physical description. 12. Which property of an object depends on its location? E. Density F. Mass G. Volume H. Weight I. The density of an object is constant. It doesn t change unless the object does. J. Mass depends on the size and/or density of an object, not its location. K. Volume also depends on the size and/or density of an object, not its location. L. Weight is the effect of gravity on an object s mass, so weight will change elsewhere in the universe with different gravitational forces. 13. How are the particles of a gas different from the particles of a liquid? E. They move more slowly F. They are farther apart. G. They have less energy H. They have stronger attractions. I. Gas particles move much faster than liquid particles. J. The forces between gas particles are weaker than liquid particles, so they re can move further apart.

4 K. Gas particles move more energetically than liquid particles. L. Gas particles have weaker attractions between them. 14. Which is a physical change? E. Burning natural gas. F. Chopping onions. G. Digesting food. H. Exploding dynamite. I. Burning natural gas creates energy, which is a chemical reaction. J. Chopping onions changes the shape of the onion (makes it smaller), which is a physical change. It does not become a new substance, so it s not a chemical change. K. New substance is formed: chemical change. L. Transformation of matter: chemical change. 15. Which stays the same when a substance changes from a liquid to a gas? E. Density F. Mass G. Forces between particles H. Distance between particles A. When a substance changes from a liquid to a gas, the particles spread out and take up more space (higher volume), so the density (mass/volume) will change B. The Law of Conservation of Mass states that the mass of a substance before a physical change stays the same after the physical change C. When a substance changes from a liquid to a gas, the forces between the molecules loosen D. When a substance changes from a liquid to a gas, the molecules spread out 16. How do weight and mass differ? E. Weight depends on the location of an object, but mass does not. F. Weight does not depend on the location of an object, but mass does. G. Weight and mass depend on the location of an object. H. Weight and mass do not depend on the location of an object. A. Weight depends on the amount of gravity acting on the mass of an object, and gravity differs based on location (space, planets, etc.) B. Gravity has no effect on mass, so it does not change regardless of where the object is located. C. Weight depends on location, mass does not. D. Weight depends on location, mass does not. 17. When a candle is lit, the wick burns, the wax melts, the candle changes shape, and the air around the candle heats up. Which of the following is an example of a chemical change? A. The wick burning. B. The wax melting. C. The candle changing shape.

5 D. The air around the candle heating up. A. Burning a substance creates a new substance, which indicates a chemical reaction. B. The wax melting changes the shape of the wax, but it s still wax, which is a physical change. C. A candle changing shape does not change the molecular makeup of the wax, so it s a physical change. D. Change in temperature is a physical change. 18. You are given a mystery object in science class. Your teacher asks you to determine if your object is more or less dense than water. You place the object in the water and it sinks. Which statement would best describe this situation? A. The mystery substance is denser than water. B. Water is denser than the mystery substance. C. They both have the same mass. D. The mystery substance must be hollow. A. Denser substances are relatively heavier than less dense subject, so it will sink. B. If the object sank, the water must have been relatively lighter, indicating that the water is less dense. C. Because density is the mass of a substance relative to its volume, without knowing the volume of each substance, you can t determine the masses of either. D. If the mystery substance was hollow, the air inside it would cause it to float, not sink. Extra Credit Draw the particle configuration of solids (1 pt.), liquids (1 pt.) and gases (1 pt.). Make sure you label which is which.
