Properties of matter

7. State of matter with definite shape and volume.
8. Change from solid to liquid.
11. Transfer of thermal energy between substances.
13. Characteristic that can be observed without changing a substance.
14. Gas law: volume and temperature are directly related.
15. Amount of matter in an object.
17. Transfer of energy through electromagnetic waves without direct contact.
18. Transfer of heat by movement of fluids (liquids or gases).
20. State of matter with no definite shape or volume.
23. Measure of the average kinetic energy of particles.
25. Energy an object has due to its motion.
28. Temperature at which a liquid changes to a gas.
29. Material that allows heat or electricity to pass through easily.

1. Gas law: pressure and volume are inversely related.
2. Law stating buoyant force equals the weight of displaced fluid.
3. Material that resists the flow of heat or electricity
4. Change from gas to liquid.
5. Change from solid directly to gas without becoming liquid.
6. Gas law: pressure and temperature are directly related.
9. Total energy of particles due to their motion and position.
10. A change that affects form but not chemical composition.
12. Force applied per unit area by particles in a gas.
13. High-energy state of matter found in stars and lightning.
14. Transfer of heat through direct contact between particles.
16. State of matter with definite volume but no definite shape.
19. Amount of space an object or substance occupies.
21. Change from liquid to solid.
22. Change from liquid to gas at the surface of a liquid.
24. Characteristic that describes a substance’s ability to change into a new substance.
26. A change that results in a new substance.
27. Mass per unit volume of a substance.
