The boiling point of a liquid is
A) the temperature at which the rate of evaporation and sublimation are equal
B) always 200$\degree$C or greater
C) the temperature at which the pressure over the liquid equals the vapor pressure of the liquid
D) the temperature at which liquid-vapor equilibrium is reached

Question

Quizplus · Accepted Answer

The boiling point of a liquid is the temperature at which the pressure over the liquid equals the vapor pressure of the liquid. At this temperature, liquid-vapor equilibrium is reached, and the liquid starts to boil and turn into a gas. Therefore, option C is the correct answer. Options A and B are incorrect as they do not define the boiling point accurately. Option D is partially correct but does not include the crucial information about pressure and vapor pressure.

The Boiling Point of a Liquid Is A) the Temperature °\degree°
