Please do all problems, show work and explain. Thank you.
What is delta S_tot, DELTA S_sys DELTA S_surroundings for a mole of perfect gas that double its volume, gets compresses again, has a cat sit on top of it, explodes, implodes, is set on fire, is laughed at by the popular kids where every process is adiabatic and reversible? what is Delta S_sys for a mole of a gas that has the volume doubled and then halved isothermally and irreversibly? what is the Delta S_tot, Delta S_sys, Delta S_surroundings for a mole of prefect gas that halves its volume isothermally and irreversibly at 50degreesC?Explanation / Answer
If all process are reversible, there is no entropy generation in any case
That is, dS System = 0, therefore dS surroudning = 0, the addition dS universe = 0
(this will never happen in real life)
b)
dSys 1 mol V2 = 2V1
S1 = R*ln(V2/V1) = R*ln(2) = 8.314*0.693 = 5.76 J/gmol K
