Internal energy and entropy?

A low-mass rigid tank contains 55.0 g of argon, initially at 230 ° C and 100 kPa. The tank is placed in storage at 0 ° C and cool thermal equilibrium. Calculate: (a) The volume of the tank ** I found 57.59 L, which is right. The rest is what I need help … (b) the change in internal energy of argon is that the change in internal energy equals W = QW and Thet Qhot-Qcold, but I'm not really sure what to plug where to get this response. (c) heat energy transferred does not even know where to start with this … (d) variation entropy of argon know that the entropy change is equal to dQ / T and dQ = MCDT. I'm not really sure what to use for what – and what the temperature change be. Is the fresh argon at 0 * C? (E) the entropy of the constant temperature bath

Dear Flossie, you need a book Physical Chemistry, and if you're pleased with so many of Partial Differential equations are very simple. a) PV = nRT is about 1.5 moles of argon. b) Du = Cv.Dt. I suppose given the specific heat capacity of argon in Volume Contant in question (2.98) c) DQ = DU + PDV. As the volume does not change the second term is zero d) dS = C, dT / T. Integrate to give: DS = Cv. (Ln (T2)-Ln (T1)) e) DS = DQ / T = DU / T = DU/273 where D stands for delta or "change" d means differential or partial differential Look at all this in a book I wrote this partly from memory, but I hope this gives you a way out .. ———– Copyleft: RC
