Use the worked example above to help you solve this problem. A cylinder contains 2.15 mol of helium gas at 18.5°C. Assume that the helium behaves like an ideal gas. (a) Find the total internal energy of the system. J (b) What is the average kinetic energy per molecule? J (c) How much energy would have to be added to the system to double the rms speed? The molar mass of helium is 4.00 10-3 kg/mol.
