Do you add or take heat away for evaporation?
Add heat/increase temperature
What does increasing the temperature of a substance do to the particle motion?
As the temperature increases, particles have more energy and move faster.
Rank the states of matter in order of increasing particle motion.
Solid, liquid, and gas
