Two systems have the following equations of state, where RR is the gas constant per mole. The mole numbers are N1 = 3 and N2 = 5. The initial temperatures are T1 = 175 K and T2 = 400 K. What is the temperature once equilibrium is reached (in Kelvin)?
The temperature once equilibrium is reached can be found from the following ideal gas law. Initially, we have
