A 1.0 mol sample of helium gas and a 1.0 mol sample of ammonia gas are held at the same temperature. Assuming both behave as ideal gases, do they have the same total internal energy?

Expert Solution

Answer : No. They do not have the same total internal energy.

Explanation:

The internal energy of a substance or a system is a definite quantity and it is a function only of state.(Chemical nature,composition,temperature ,pressure and volume)

The chemical nature includes such factors as the translational,rotational and vibrational motions of the molcules, the manner in which the molecules are put together, the nature of the individual atoms, the arrangement and number of electrons , the energy possessed by the nuclei etc

Since the chemical nature is different, 1.0 mol sample of helium gas and a 1.0 mol sample of ammonia gas at the same temperature will not have the same total internal energy.
