Question

A chamber fitted with a piston contains 1.70 mol of a monatomic ideal gas that is taken from an initial state i to a final state f via states 1 and 2. The chamber volume is initially Vi = 0.100 m3 and the temperature is Ti = 273 ∘C. To take the gas to state 1, it is heated isochorically to T1 = 373 ∘C. To take it to state 2, it is heated isobarically to T2 = 473 ∘C. Finally, the gas is allowed to expand isothermally until its volume is Vf=2V2. Part A What is the change in entropy of the gas?
