Consider 1 kg of helium at 500 k. assuming that the total internal energy of helium is due to the mean kinetic energy of each atom summed over all the atoms, calculate the internal energy of this gas. note: the molecular weight of helium is 4. recall from chemistry that the molecular weight is the mass per mole of gas; that is, 1 mol of helium contains 4 kg of mass. also, 1 mol of any gas contains 6.02 × 1023 molecules or atoms (avogadro’s number).
