Consider the change that occurs in the shape of the Maxwell-Boltzmann distribution curve for molecular energies in a gas when the temperature of the gas is decreased.
Which is a correct statement about the gas molecules at the lower temperature?
The mean energy of the molecules increases.
There is an increase in the number of molecules with the most probable energy.
The area under the distribution curve increases.
The most probable energy of the molecules increases.
