A three level system has energies 0=0.00J,1=5.001021J, and 2=10.01021J. Part A Using the Boltzmann Distribution Law, calcuate the molar internal energy U at T=10.0K. Hint: This means you have to calculate three probabilites at T=10K and use them to calculate the average energy per particle...and then calculate the energy of a mole of particles
