Consider a scuba tank (12.0 L volume) initially at 1.00 atm that is subsequently filled to 200atm with oxygen (average M ~ 32.00 g/mol, Cp! = 29.355 j.mol^-1k^-1) behaving as an ideal gas. Assuming the tank is sitting in water at 298 K at an external pressure of 1.00 atm, filling the tank can be considered an isothermal and reversible process. (a) Calculate the molar change in the internal energy and enthalpy of the gas inside and outside the tank.Also, calculate the amount of work required to fill the tank and the amount of heat transferred to the surrounding water. (b) What is the mass of gas present in the tank once it is filled? (c) Assuming the tank is surrounded by 1.00 m3 of water and using the heat capacity and density (293 K value) for water found in the back of your textbook, calculate the temperature change of the water (Qp = CpΔT)
