  2. 2. water vapor - water in its gas form is water vapor. If you can see it, it’s not really water vapor! <br />
  3. 3. humidity – the level of moisture in the air; the amount of water vapor in the air<br />
  4. 4. relative humidity – is when you compare how much water vapor is in the air to how much it COULD hold<br />
