A certain perfect gas has Cv,m = a + bT where a = 25.0 J mol-1 K-1 and b = 0.03 J mol-1 K-2. Let 4.00 mol of this gas go from 300 K and 2.00 atm to 500 K and 3.00 atm. Calculate each of the following quantities for this change of state. If it is impossible to calculate a quantity from this given information, state this. (a) q; (b) w; (c) ?U; (d) ?H.
