Unit 2 Thermal Energy

3. transformation, a change of energy from one form to another
6. the state of matter that has a definite volume but not a definite SHAPE
7. light energy hits a surface and converts into heat energy
10. A measure of how HOT or cold something is; specifically, a measure of the average kinetic ENERGY of the particles in an object.
14. The change of state from a gas to a liquid - when a cold SURFACE meets warmer AIR.
17. A measure of the amount of MATTER in an object
18. variable, Factor in an experiment that a scientist purposely keeps the SAME

1. variable, The experimental factor that is manipulated or CHANGED; the variable that CAUSES the effect that is being studied.
2. A state of matter that has a DEFINITE shape & a definite VOLUME
4. variable, The RESULT or effect being measured; the variable that may change in RESPONSE to manipulations of the independent variable
5. energy, the total energy of motion in the particles of a substance
8. System, matter can LEAVE from or ESCAPE to the surroundings Energy can also escape
9. A small portion of MATTER
11. The change of state from a LIQUID to a GAS.
12. A state of matter with no definite shape or VOLUME
13. energy, the energy of motion
15. transfer, movement of energy from one place or object to another
16. system, matter is NOT able to enter or LEAVE a system Energy can escape
