Physics

Estimatethe total entropy change when 100.g of liquid water,initially at 298 K and 0.50 atm,is first heated to boiling at 373 Kand 1.00atm, and the steamcollected at 1.00 atmsubsequently heatedand compressed to 500Kand20.atm. UseDHvap(at 100 ÌŠC, 1 atm)= 40.6kJ/mol and the following values for the heat capacity:CP,m(H2O,l) =75.2 J/(K mol), CP,m(H2O,g) = 35.0J/(K mol)
