Question

An insulated vessel has an evacuated compartment (V = 100 L) separated from a second compartment (V = 100 L) which contains air at 100 oC, 202.7 kPa. The partition now ruptures and the air expands to fill the entire volume. Assume that the constant-volume specific heat of air remains constant at 0.720 kJ/kg-K. Taking the air as the system, determine for the process the:

(a) Work, in kJ
(b) Heat, in kJ
(c) Entropy change of the air, kJ/K
(d) Entropy change of the air plus the surroundings, in kJ/K. Is this process reversible,

irreversible, or impossible?

I am not really sure how to solve this problem, I would really appreciate it if someone can help out. Thank you so much!!

Explanation / Answer

as the given vessel is insulated process is adiabatic so heat gained =o.
