One mole of hydrogen gas at temperature T is mixed with one mole of helium gas at temperature 2T in an isolated vessel. The equilibrium temperature of the gas mixture is

View answer and explanation

Correct option: A

\frac{{11}}{8}T

Option A (

\frac{{11}}{8}T

) is correct because the equilibrium temperature is found by equating the total internal energy before and after mixing.
