Ideal Gas Equation

Kinetic energ...

Question

Kinetic energy of a molecule is zero at _____ K.

Open in App

Solution

The total kinetic energy of gas depends only upon temperature.
A decrease in temperature results in a decrease in kinetic energy of molecules.

Also, $K E = \frac{3}{2} R T$

Thus, kinetic energy of a molecule is zero at 0 K
