Q. The average kinetic energy of a gas molecules is
A) Proportional to pressure of gas
B) Inversely proportional to volume of gas
C) Inversely proportional to absolute temperature of gas
D) Directly proportional to absolute temperature of gas
Explanation
(d) Average kinetic energy $E = \frac{3}{2}kT$
$\Rightarrow \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ E \propto T$
Thus, average kinetic energy of a gas molecule is directly proportional to the absolute temperature of gas.
