States of Matter

3. (molecular) theory is an explanation of the behavior of particles in gasses; states that matter is made of constantly moving particles that collide without losing energy
5. the conversion of a solid or liquid into a gas; the two types of vaporization are evaporation and boiling
6. The state of matter that particles move randomly and constantly
8. matter that has enough energy to overcome not just the attractive forces between its particles but also the attractive forces within its atoms.
11. action of bringing a liquid to the temperature at which it bubbles and turns to vapor
12. (heat of)is the amount of energy required for the liquid at its boiling point to become gas
14. energy Energy a moving object has because of its motion; determined by the mass and speed of the object
18. when a liquid changes into a solid
19. altered from a solid to liquid usually by heat
21. Physically distinctive form of matter (solid, liquid, gas)

1. a change from one state (solid, liquid, or gas) to another without a change in chemical composition
2. (heat of) The energy required to change a substance from solid to liquid at its melting point.
4. the process where water changes from a liquid to a gas
7. A sample of matter that retains its shape and density when not confined
9. conversion of a substance from the solid to the gaseous state without it becoming liquid
10. a substance that flows freely but is of constant volume
13. expansion-increase in the size of a substance when the temperature is increased
15. the process where water vapor(gas)becomes liquid
16. (The ability to cause change, measured in joules
17. energy is stored energy due to the interactions between objects
20. energy Sum of the kinetic and potential energy of the particles that make up an object
