- Homework Statement
- An insulated rigid tank is initially evacuated. A valve is opened, and atmospheric air at 95 kPa and 17 C enters the tank until the pressure in the tank reaches 95 kPa, at which point the valve is closed. Determine the final temperature of the air in the tank. Assume constant specific heats.

- Relevant Equations
- Cp=dh/dt

CV=du/dt

The solution can be found at https://study.com/academy/answer/an-insulated-rigi...

After using the two equations I can't see

why (h2-h1)/(u2) should equal (T2)/(T1).

Can someone explain why specific heat ratio is equal to temperature ratio?
