Determine ssys separately for the volume and temperature, Ask an Expert

Academics

2. 2.3 mol of helium at 20°C and 5.0 atm are allowed to expand reversibly and adiabatically until the pressure reaches 1.0 atm.

a. Determine Ssys separately for the volume and temperature changes and show that ?Ssys = 0 for a reversible adiabatic process.

b. If the expansion had instead occurred irreversibly against a constant external pressure of 1 atm, now what are ?Ssys, ?Ssur, and ?Suniv?
