1. Solids, Liquids, and Gases
(IC Chapter 2 Test Review)

2. The surface of water can act like a sort of skin due to a property of liquids called this.
surface tension

3. The is the state of matter that undergoes changes in volume most easily.
gas

4. According to Charles’s law, when the temperature of a gas at constant pressure is increased, this happens.
volume increases

5. This is the change from a liquid to solid, or the reverse of melting.
freezing

6. vaporization, then condensation
An uncovered pot of soup is simmering on a stove, and there are water droplets on the wall above the back of the stove. This is the sequence you can infer has occurred.
vaporization, then condensation

7. In cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. This is the process that best explains this event.
sublimation

8. This is the state of matter in which particles are arranged in either a crystalline or an amorphous form.
solid

9. The greater the speed of gas particles in a container, the...
greater the pressure

10. This is the unit used for pressure.
newtons per square meter

11. According to Boyle’s law, this is what happens to the volume of a gas when the pressure is increased.
it decreases

12. This is the state of matter in which particles are arranged in the least organized manner.
gas

13. When a substance cools, it loses this type of energy to its surroundings.
thermal

14. This is the change of a solid directly into a gas.
sublimation

15. This is a liquid’s resistance to flowing.
viscosity

16. This occurs when a liquid changes to a gas below its surface as well as at the surface.
boiling

17. The particles in this type of solid are not arranged in a regular pattern.
amorphous

18. At this temperature, the particles of a liquid are moving so slowly that they begin to form regular patterns.
freezing

19. This is the process where pieces of dry ice (solid carbon dioxide) become smaller.
sublimation

20. GOOD LUCK!!!!
