Question

multiple choice question
liquids evaporate relatively low temperatures because
o most liquids boil at relatively low temperatures
o low temperatures are always accompanied by a decrease in atmospheric pressure
o some of the liquids molecules have high enough energy to escape into the surrounding atmosphere as a gas
need help? review these concept resources.

Explanation:

Evaporation is a surface - level process. In a liquid, molecules have a distribution of kinetic energies. At relatively low temperatures, some molecules near the surface have sufficient kinetic energy (higher than the average) to overcome the intermolecular forces holding them in the liquid phase and escape into the gas phase. Boiling is a bulk phenomenon that occurs at a specific temperature (boiling point) for a given pressure. The statement “low temperatures are always accompanied by a decrease in atmospheric pressure” is incorrect as temperature and atmospheric pressure are not always directly related in that way.

Answer:

some of the liquid's molecules have high enough energy to escape into the surrounding atmosphere as a gas
