1. Direct change of a substance from the solid to the gas state, without passing through the liquid state. ______________________________
2. The state of matter that exists due to a high amount of energy and the particles break apart into positive and negative ions. ______________________________
3. A change of state from a liquid to a gas that takes place below boiling point. ______________________________
4. Described as energy that flows from one object to another due to differences in temperature. Flows from a warmer material to a cooler material ______________________________
5. A term used to describe any substance that flows, mainly liquids and gases. ______________________________
6. Anything that can change the condition of matter. ______________________________
7. The number of calories required to raise the temperature of one gram of substance one Celsius degree. ______________________________
8. Measure of the average kinetic energy of the particles that makes up a sample of matter. Relative hotness/coldness. ______________________________
9. Mass of a substance per unit volume. ______________________________
10. State of matter in which all the particles are packed tightly with what little motion due to vibrations of the particles. _____________________________
11. State of matter in which particles move freely of one another and
only sporadic contact. _____________________________
