1.2 Introduction to Energy

1. Kinetic Energy: The mathematical average of the individual kinetic energies of all particles in a substance.
7. The study of energy changes that happen during chemical reactions and changes in state.
8. Anything that has mass and takes up space.
9. The temperature scale that is generally not used in scientific investigation.
11. Energy that transfers from one object to another because of temperature differences.
12. The movement of heat, which always travels from warmer objects to cooler ones.
13. The very small particle that composes all ordinary matter.
14. Energy: The total kinetic energy possessed by all individual particles in a substance.
16. of Energy: Another name for the First Law of Thermodynamics.
17. The SI temperature scale that starts at absolute zero and does not use degrees.
18. Energy: The energy of an object’s motion.

2. A process driven by the transfer or transformation of energy.
3. One of the two temperature scales used in science; water freezes at 0 on this scale.
4. The study of matter, its interactions, and the changes it undergoes.
5. The specific part of the universe being investigated during a change.
6. A measure of the average kinetic energy of the particles in matter.
10. Energy: The energy that is stored within a system.
15. Law of Thermodynamics: The law stating that energy is never created or destroyed, only changed.
16. Potential Energy: Energy stored specifically within the bonds of molecules.
19. The capacity to move, do work, change matter, or produce heat.
