Unit 3 Active Study

3. The transfer of thermal energy from a warmer object to a cooler one until they reach the same temperature.
5. The transfer of heat through direct contact between materials
7. The process of changing energy from one form to another
12. The transfer of heat through the movement of fluids (liquids or gases), where warm substances rise and cooler ones sink.
14. An energy source that takes millions of years to form from the remains of plants and animals.
15. An energy resource such as trees or wind that is replaceable by natural means.
16. radiant energy from the sun that can be transformed into electric energy.(renewable)

1. When two objects have reached the same temperature and no heat flows between them.
2. A measure of the average kinetic energy of particles in a substance - how hot or cold something is.
4. Anything that has mass and takes up space
6. Movement of water through a dam in a river is converted to useable energy (renewable)
8. The transfer of heat or energy through electromagnetic waves
9. The sum of the potential and kinetic energy in a substance
10. Fuels A natural nonrenewable fuel formed over a very long time in the past from the remains of living organisms.
11. turbines harness the movement of air and convert it to useable energy (renewable)
13. The energy an object has due to its motion
