Phase Changes

2. A phase change, it is the most dense
6. Gas to liquid
8. Liquid to gas, on surface
9. Solid to liquid
11. How much matter an object takes up
13. How much space an object takes up in relation to the amount of matter in that object
17. The average kinetic energy of the molecules
19. What it's called when the volume of a substance is not changing
20. The degree of temperature that water melts/freezes
21. When pressure is constant, temperature goes up and volume goes up and vice versa
22. Solid to gas, skipping liquid
23. A phase change, it has the most volume
24. A change in state of matter that does not change the identity of the substance

1. Gas to solid, skipping liquid
3. The degree of temperature that water evaporates/condenses
4. Liquid to gas, when boiled
5. Liquid to gas
7. Liquid to solid
10. A phase change, it is viscous
12. When temperature is constant, pressure goes down and volume goes up and vice versa
14. The total kinetic energy in a substance
15. When volume is constant, temperature goes up and pressure goes up and vice versa
16. The unit of temperature used in science
18. A change in state of matter that changes the identity of the substance
