7th grade midterm

3. the transfer of thermal energy from a warmer object to a cooler object.
6. the highest point on a transverse wave
8. waves bending around an object.
9. the transfer of thermal energy by the movement of a fluid.
11. a measure of the average kinetic energy of the particles of a substance.
12. a material that does not conduct heat well
14. the number of wavelengths that pass a fixed point each second. It can also be thought of as the number of times a wave repeats in a given amount of time
17. a material that conducts heat well.
19. a state of matter that has a definite shape and a definite volume.

1. the dense part of a longitudinal wave
2. the transfer of the energy of a wave to a material it encounters.
4. the bouncing back of a wave when it hits a surface through it cannot pass.
5. a state of matter that has no definite shape or volume.
7. the transfer of energy by electromagnetic waves.
10. the lowest point on a transverse wave.
13. the areas of a longitudinal wave between the compressions.
15. the bending of waves as they enter a new medium at an angle, caused by a change in speed.
16. the transfer of energy from one particle of matter to another by direct contact of the particles.
18. a state of matter that has no definite shape but has a definite volume.
