Answer to Question #67518 in Mechanics | Relativity for Mai

Question

9/ A 2.0 mol sample of an ideal monatomic gas undergoes a reversible process at constant volume, increasing its temperature from 400 K to 600 K. What is the entropy change of the gas?

10/ Calculate the change in entropy of gases in the following cases:
a) A 3.0 mol sample of an ideal gas expands reversibly and isothermally at 350 K until its volume doubled.
b) The temperature of 1.0 mol of an ideal monatomic gas is raised reversibly from 200 K to 300 K, with its volume kept constant.
