We have seen in class that the energy of an ideal monatomic gas per molecule is given by 3kpT/2. (Recall that in an ideal gas, the molecules do not interact, hence the potential energy is equal to zero. As a result, the total energy is equal to the total kinetic energy of the molecules. Since m = 3kgT, we obtain m/2 =3kgT/2.) This is an example of the so called equipartition theorem: The kinetic energy is partitioned equally among the molecules, regardless of their chemical identity. Compute the energy of 1 L of a monatomic ideal gas at SATP (standard ambient temperature and pressure), in Joules. Selected Answer: @ 166 Correct Answer: 150
