Suppose That an Atom Has Exactly Two Energy Levels Separated $\Delta \mathrm{E}$

Multiple Choice

Suppose that an atom has exactly two energy levels separated by an energy difference $\Delta \mathrm{E}$ . When such atoms are in contact with a reservoir at a temperature $T_{1}$ , the ratio of the number of atoms in the higher level to the number in the lower level is $\frac{1}{4}$ . If we increase the temperature to $T_{2}$ , the numerical value of this ratio

A) increases.
B) decreases.
C) remains the same.
