Entropy changes: Consider samples of 1 mol of N₂(g) at 300K and 1 mol of O₂(g) at 200K. The same amount of heat is added to each sample and as a result the entropy of the samples are changed. The entropy of which sample will change more and why did you choose it? b. To have both samples undergo the same entropy change, would more heat need to be added to the N₂ gas or the O₂? Justify your answer. c. Calculate the change in entropy if the temperature of the N₂ is lowered from 300K to 200K. Cp,m = 29.1 J/K mol for N₂.
