Evaporating is when
  1. a substance changes from a liquid to a gas by heating it to its boiling point (i.e water in a kettle turning to water vapor).
  2. a substance changes from a liquid to a gas (or vapor) naturally (ie. when a puddle dries by the water in it evaporating).
  3. a substance changes from a gas (or vapor) into a liquid (ie. water vapor condenses to tiny droplets of water on a cold window).

  2. law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as its pressure decreases and the volume of the gas decreases as its pressure increases.
  3. term used to describe a physical or chemical change in which energy is given of.
  4. physical forms in which a substance can exist; includes solid, liquid, gas, and plasma.
