Find the correct answer within the parentheses 1.The (faster, slower) particles move, the more kinetic energy they have.

2.Particles in the (solid, gaseous) state have the most kinetic energy.

3.Temperature is the measure of the average kinetic (substance, energy) of all particles in an object.

4. When the temperature of a substance (increases, decreases), particles move slower.

5.Potential energy (increases, decreases) as particles get farther apart.

6.Thermal energy is the (product, sum) of potential and kinetic energy.

7.When thermal energy is added to a liquid, kinetic energy (increases, decreases).

8.As a liquid changes to a (gas, solid), the particles move farther apart
