Temperature is a measure of a substance's average
kinetic energy
heat
density
electrostatic force
"Kinetic" refers to
motion

Two identical beakers each contain water. The temperature of each is 20oC. Which one has more heat energy and why?
They both have the same amount of heat energy because the temperature is the same
The one on the right has more heat energy because there is more water
The one on the left has more heat energy because there is less water.
Evaporation is what kind of change and WHY?
Endothermic because it requires energy
Exothermic because it requires energy
Endothermic because it releases energy
Exothermic because it requires energy
