Temperature

2. the energy transferred between objects that are at different temperatures
4. a device that measures heat.
8. the lowest temperature on the kelvin scale {0 K}
9. a material through which energy can be transferred as heat
10. the circular motion of liquids or gases due to density differences that result from temperature differences
12. the process earth allows the suns visible light to pass through it.
14. a measure of the average kinetic energy of the particles in the object
15. gases that allow the atmosphere to trap the suns energy. (water vapor, carbon dioxide, and methane)
17. the total kinetic energy of the particles that make up a substance
18. the transfer of energy as electromagnetic waves

1. a material that reduces or prevents the transfer of heat
3. the transfer of thermal energy from one substance to another through direct contact.
5. small gaps on a bridge that keep segments of the bridge apart so they have room to expand without the bridge expanding
6. the rate at which a substance conducts thermal energy
7. made of two different metals stacked in a thin strip
11. the increase in volume of a substance because of an increase in temperature
13. the transfer of thermal energy by the circulation or movement of a liquid or gas
16. the amount of energy needed to change the temperature of 1 kg of a substance by 1 C
