Question 192

Which statement correctly compares evaporation and boiling?

A

Evaporation only occurs at the boiling point, whereas boiling occurs at any temperature.

B

Evaporation occurs only at the surface of a liquid, whereas boiling occurs throughout the liquid.

C

Evaporation leads to an increase in the temperature of the remaining liquid, whereas boiling maintains a constant temperature.

D

Thermal energy is absorbed during boiling, but no thermal energy is absorbed during evaporation.
