Concept introduction:
Different linearly independent wavefunctions that have same energy are called degenerate. This is expressed in terms of degeneracy. If two functions are having same energy then they are called doubly degenerate and so on. The electronic partition function is represented as,

- For two nondegenerate energy levels separated by an amount of energy ε/k=500.K, at what temperature will the population in the higher-energy state be 1/2 that of the lower-energy state? What temperature is required to make the populations equal?arrow_forwardAt temperature T, the internal energy of 1mol rigid diatomic molecules is =......arrow_forwardA standard sample of Argon gas is 22.4L, 1.00atm, 1.00mol, 273.15K. In the right setups excited gas can be tricked into using heat and giving away photons of light. If the sample gave off 0.01mol of 3,634nm light by converting thermal energy into those photons find the new final temp of the gas. SAr = 0.52J/gKarrow_forward
