A tank is being filled through a valve by an ideal gas where the following applies: H=30*T(K) in J/mol for gas, R=8.314 in J/mol/K, H=40 T(K) for the liquid in J/mol (gas as liquid, different reference point than gas), the entering gas is at 336K and flowing at 0.7 mol/s, and 2 moles of gas are in the tank at 262K. What is the rate of change of temperature in the tank in J/s?
