A metallic tank contains ten moles of gas. This tank is at T-450 K and the gas is initially at P = 0.7 bar and also at T = 450 K. You then take this tank and place it inside a furnace which is at a constant T = 600 K. The tank and the gas inside eventually reach thermal equilibrium with the furnace. We would like to make some thermodynamics calculation and for that you can assume the gas to be an ideal gas at the pressures attained throughout this process. You may also assume the gas has a constant heat capacity of Cv* = 2.5R. The mass of the tank alone is 11 kg (not including gas mass inside the tank) and its specific heat capacity of Cv= 1.5 J/g•K. Find the Following: The amount of heat added to the gas The change in entropy of the universe C. Discuss briefly if the process is irreversible or not

Question

A metallic tank contains ten moles of gas. This tank is at T-450 K and the gas is initially at P = 0.7 bar and also at T

= 450 K. You then take this tank and place it inside a furnace which is at a constant T = 600 K. The tank and the gas

inside eventually reach thermal equilibrium with the furnace. We would like to make some thermodynamics calculation and for that you can assume the gas to be an ideal gas at the pressures attained throughout this process.

You may also assume the gas has a constant heat capacity of Cv* = 2.5R. The mass of the tank alone is 11 kg (not

including gas mass inside the tank) and its specific heat capacity of Cv= 1.5 J/g•K.

Find the Following:

The amount of heat added to the gas The change in entropy of the universe

C. Discuss briefly if the process is irreversible or not
