A rigid, insulated tank is initially evacuated. The tank is connected with a supply line through which air (assumed to be ideal gas with constant specific heats) passes at 1 MPa, 350°C.
A valve connected with the supply line is opened and the tank is charged with air until the final pressure inside the tank reaches 1 MPa. The final temperature inside the tank
-
- is greater than 350°C
- is less than 350°C
- is equal to 350°C
- may be greater than, less than, or equal to 350°C, depending on the volume of the tank.
Correct Option: A
Greater than 350°c (∵ Tf = γTi)
