An initially evacuated tank has a valve at the tank inlet. The valve is opened to the atmosphere until the air pressure in the tank reaches 50 kPa. The valve is then closed and the tank is allowed to come to thermal equilibrium with the surrounding atmospheric air.
During this process:
a. Heat is transferred from the tank to the atmosphere.
b. Heat is transferred from the atmosphere to the tank.
c. No heat is transferred.
d. Not enough information.
