Question

Interatomic molecular forces explain many bulk properties of matter. Which of the following statements is true?

A. In solids, the potential energy and kinetic energy are equal

B. In gases, the potential energy is far greater than the kinetic energy

C. In solids, the potential energy is far greater than the kinetic energy

Answer 1

Answer:

Intermolecular forces determine bulk properties such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.

Answer 2

Answer:

Therefore, option (B) is correct because,

Strong intermolecular forces slow down the rate of evaporation. If the intermolecular forces in the liquid are small, the molecules need little energy to separate from each other. The molecules escape into the atmosphere. The rate of evaporation is high.
