insulator a material that heat does not move through easily
solid matter that has a definite , or certain, amount os space
conductor a material that heat easily moves through
temperature the measure of how hot or cold something is
What states of matter can change shape? gases and liquids
The more thermal energy an object has, the ___________ the temperature. higher
High temperature = fast particle movement
Low temperature = slow particle movement
When does an object expand? when the temperature increases
When does an object contract? when the temperature decreases
Which state of matter has the particles most closely packed together? solid
Which state of matter has the particles with the most space between them? gas
