`T_(1)` is the temperature of oxygen enclosed in a cylinder. The temperature is increased to `T_(2)` and Maxwellian distribution curves for `O_(2)` at temperatures `T_(1) and T_(2)` are plotted. If `A_(1) and A_(2)` are the areas under the curves and the speed axis, in both cases, then

Options

A. `A_(1)gtA_(2)`
B. `A_(1)ltA_(2)`
C. `A_(1)=A_(2)`
D. `A_(1)=sqrt(A_(2))`

Answer

C

Explanation

The Maxwellian distribution curves will be different. But the areas under them will be equal `(A_(1)=A_(2))`. Because the area gives the total number of molecules, which remains constant.
