Question

Take two containers, each with volume 0.1 m3, containing ideal gases of monatomic He at T= 104 K and diatomic N2 at T = 236 K, respectively. Each gas is at pressure p= 106 Pa. A valve is opened allowing these two gases to mix.
What is the change of dimensionless entropy solely due to the fact that the gases have more volume accessible?
What is the change of dimensionless entropy solely due to the fact that the gasses' temperatures have changed?
What is the change of the standard entropy in this process? ?
