Nature of Matter Chap 2

2. The change from a liquid to a gas.
4. Attractive forces cause particles to pull themselves together acting as a thin film stretched across the surface of a liquid.
5. the total energy of all the particles in a sample of matter.
8. the physical state of air.
13. When something is heated, it gains thermal energy causing its particles to move faster and its temperature ____________.
14. Particles of solid matter exhibit this type of motion.
15. The average kinetic energy of the individual particles in a substance.
18. The process of gas condensing to a liquid.
20. The energy of motion.
22. This type of solid contains particles that have a random arrangement. Example: plastic.
23. The process of a substance changing from the solid state to the gas without ever becoming a liquid.

1. The amount of heat needed to raise the temperature of 1 g of a substance 1˚C.
3. when a warm object is brought near a cooler object, thermal energy will be ____________ from the warmer object to the cooler one.
6. Vaporization that takes place at the surface of a liquid.
7. Vaporization that takes place below the surface of a liquid.
9. The _______ between the particles in a solid are strong enough to hold the particles in fixed positions, they vibrate in place.
10. What is matter made up of?
11. The change from the liquid state to the solid state.
12. This type of solid contains particles arranged in repeating, three-dimensional patterns. Example: diamond.
16. A liquid’s resistance to flow based on the strength of the attraction between the particles in the liquid.
17. The change from the solid state to the liquid state.
19. One of the physical states of matter.
21. This state of matter maintains its shape and volume.
24. One of the three types of particles.
