State's of Matter

2. the temperature at which a solid becomes a liquid
6. the amount of energy required for a liquid to change into a gas
8. the process in which a gas changes directly into a solid
12. material substance that occupies space has mass and is composed predominantly of atoms
13. has a definite volume but not shape because its particles flow and don't move as fast as in a gas
14. the temperature at which a liquid boils
15. it doesn't have a fixed volume or shape because its particles are in constant movement
16. the process in which a liquid's particles overcome the attractive forces and become a gas

1. it is an explanation of how particles in a gas behave
3. the process in which a gas becomes a liquid
4. occurs at the surface of a liquid and can happen at nearly any temperature
5. occurs through a liquid at a specific temperature
7. the process in which a solid changes directly into a gas
9. the process in which a liquid changes into a solid because its particles lose kinetic energy and stay fixed in one place
10. the energy required for a solid to change into a liquid
11. it has a definite shape and volume because its particles are closely packed together
12. the process in which a solid becomes a liquid
