Question

Container A has a sample of monatomic ideal gas, while container B has a sample of diatomic ideal gas. The two gases start with the same initial temperature, volume, pressure, and number of moles of molecules. Each gas now undergoes a reversible adiabatic process that cuts the pressure in half. Which sample of gas is now at the higher temperature?

T f ​ = T i ​ ( P i ​ P f ​ ​ ) ( γ − 1 ) / γ = T i ​ 2 − ( γ − 1 ) / γ . Monatomic: exponent 5 2 ​ ; diatomic: 7 2 ​ . The diatomic gas cools less, so container B is warmer.
