Across
- 2. To strike or hit something with any amount of force
- 4. Anything that has volume and mass; occurs as elements, compounds, and mixtures
- 9. When a sample of matter changes from a liquid to a solid
- 10. defines how two different systems can be said to be at the same temperature.
- 11. force exerted on matter through contact with other matter; affects melting and boiling points
- 13. the sum of all the kinetic and potential energies of all the particles within a system
- 15. A form of matter with an indefinite shape and volume
- 17. Distinct forms of matter known in everyday experience; include solid, liquid, and gas; also referred to as phases
- 20. The sum of all of the kinetic energy (KE) and potential energy (PE) found within a substance
- 21. the total kinetic (motion) energy of the tiny particles that make up matter. The faster the particles move, the warmer the matter becomes
Down
- 1. Energy that is stored in a system or object
- 3. Energy of motion
- 5. Movement of energy from one system to another
- 6. Average kinetic energy of all the particles in a material; measured by a thermometer in degree (usually Celsius or Fahrenheit)
- 7. The simplest unit of a chemical compound that can exist; formed when two or more atoms join together chemically
- 8. Energy transferred between two objects of different temperatures moving continually in a predictable pattern, from a warmer site to a cooler site until all sites have reached the same temperature
- 12. the action of bringing a liquid to the temperature at which it bubbles and turns to vapor
- 14. A state of matter with a definite volume but no definite shape
- 16. A state of matter with a definite volume and shape
- 18. When a sample of matter changes from a solid to a liquid
- 19. The process by which a sample of matter changes from a gaseous state to a liquid state
