To give a helium atom nonzero angular momentum requires 21.2 eV of energy, meaning that 21.2 eV is the difference between the energies of helium’s ground state and of the lowest-energy state in which a helium atom has nonzero angular momentum. Find the lowest temperature at which helium atoms possess angular momentum if the energy required to give a helium atom nonzero momentum equals Boltzmann’s constant multiplied by .
What is the internal energy of 6.00 mol of an ideal monatomic gas which has a temperature of ?
0.82 mol of dilute carbon dioxide at a pressure of 1.80 atm occupies a volume of 58 L. What is the internal energy of the gas?
