Question

ch 6 water and atmospheric moisture: waters unique properties
which of the following is associated with evaporation?
water molecules release energy
water molecules speed up and break free of each other
water vapor forms a cloud
evaporation is a cooling process
it is usually associated with rising temperatures

Explanation:

Evaporation occurs when water molecules gain enough energy (usually from heat) to speed up. This increased kinetic energy allows them to break free from the intermolecular forces holding them in the liquid state. As the faster - moving (more energetic) molecules escape, the average energy of the remaining molecules in the liquid decreases, which is why evaporation is a cooling process. Water molecules releasing energy is more related to condensation (a reverse process of evaporation). Water vapor forming a cloud is condensation (gas to liquid - like droplets in a cloud). Evaporation is a cooling process, so it is not usually associated with rising temperatures (though higher temperatures can increase the rate of evaporation, the process itself cools the surface from which evaporation occurs).

Answer:

Water molecules speed up and break free of each other, Evaporation is a cooling process.
