Question

Heat capacity of a diatomic gas is higher than that of monoatomic gas.
If true enter 1, else enter 0.

Answer 1

True.

Let us give the same amount of energy to the mono- and di-atomic gases.

The mono-atomic gas will spend all energy on translation and result in temperature rise.

The di-atomic gas will spend that energy on translational as well as rotational motion. This way, the translational component gets lesser fraction of the same energy, causing lower temperature rise compared to the mono-atomic gas.

So, to have same temperature rise, we need to give the di-atomic gas more energy. In other words, it has more specific heat.
