1) Given dU = CvdT, show (in three or more steps) that ΔU = CvΔT. All steps must be mathematically correct.
2. Given dH = CpdT, show (in three or more steps) that ΔH = CpΔT. All steps must be mathematically correct.
3. Given dH = Cp,mdT, show (in three or more steps) the expression for ΔH. All steps must be mathematically correct. Cp,m = a+bT+c/T2.
4. For a linear molecule, the molar heat capacity at constant volume is given by Cv,m = (∂Um/∂T)v. Calculate the value of Cv,m (J/moleK).
