Question

what happens when a liquid is heated?
select all that apply
a atmospheric pressure increases.
b vapor pressure decreases.
c kinetic energy increases.
d vapor pressure increases.

Explanation:

When a liquid is heated, the kinetic energy of its molecules increases because temperature is a measure of the average kinetic energy of the molecules. As for vapor pressure, it is the pressure exerted by the vapor of a liquid in equilibrium with its liquid phase. Heating a liquid gives more molecules enough energy to escape into the vapor phase, so vapor pressure increases. Atmospheric pressure is mainly determined by the weight of the air column above and is not affected by heating a liquid.

Answer:

C. Kinetic energy increases, D. Vapor pressure increases.
