At absolute zero, the molecules of a gas come at perfect rest.

Explanation

To prove that at absolute zero, the molecules of a gas come to perfect rest, we can follow these steps:

### Step 1: Understand the relationship between temperature and kinetic energy
The total kinetic energy (KE) of a gas molecule at any temperature (T) is given by the formula:
\[ KE = \frac{3}{2} k T \]
where \( k \) is the Boltzmann constant and \( T \) is the absolute temperature in Kelvin.

### Step 2: Substitute absolute zero into the kinetic energy formula
