some move at high speeds while others move hardly at all and then they can switch.
it is a cooling process because the molecules that break free from the surface of the liquid are slowed as they fly away due to their attraction to the surface. the water is cooled.
evaporation is the phase change from liquid to gas
condensation is the phase change from gas to liquid
relative humidity - the ratio of the amount of water vapor currently in the air as a given temperature to the largest amount of water vapor the air can contain at that temperature
when balls bump into one another and some gain kinetic energy, the others lose the same amount
fog is a cloud that forms near the ground.
boiling - change of phase throughout a liquid rather than only at the surface. bubbles in the liquid can form only when the pressure of the vapor within the bubbles is great enough to resist the pressure of the surrounding liquid.
