Heat energy is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point. In fact, the process of evaporation removes heat from the environment. Which of
these every day examples illustrates how evaporation removes heat from the environment?
A)
sweating cools you
B)
fog forming over a lake in the early morning
C)
water that drips off the outside of your glass of water
