Across
- 1. the smallest particle of an atom
- 5. anything that has volume and mass
- 8. average kinetic energy of all the particles in a material; measured by a thermometer in degrees
- 9. distinct forms of matter known in everyday experience: solid, liquids, and gas; also referred to as phases
- 10. energy of motion
- 11. the simplest unit of a chemical compound that can exist, formed when two or more atoms joins together chemically
Down
- 2. the total kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes
- 3. energy transferred between two objects of different temperatures in a predictable pattern; always moves from high to low
- 4. the sum of all the kinetic energy (KE) and potential energy (PE) that is found within a substance
- 6. energy that is stored in a system or object
- 7. movement of energy from one system to another
