Heat capacity of a diatomic gas is higher than that of a monoatomic gas.

Explanation

To determine whether the heat capacity of a diatomic gas is higher than that of a monoatomic gas, we can follow these steps:

### Step 1: Understand Heat Capacity
Heat capacity is the amount of heat required to change the temperature of a substance by one degree Celsius. It is related to the degrees of freedom of the gas molecules.

### Step 2: Degrees of Freedom
The degrees of freedom for a gas molecule depend on the number of atoms in the molecule:
- For a monoatomic gas (like helium), the degrees of freedom are 3 (translational motion).
