3 moles of an ideal monoatomic gas at a temperature of 27oC are mixed with 2 moles of an ideal monoatomic gas at a temperature 227oC. Determine the equilibrium temperature of the mixture, assuming no loss of energy.
Energy possessed by the ideal gas which is at 27oC is
Energy possessed by the ideal gas which is at 227oC is
If T be the equilibrium temperature of the mixture, then its energy will be
Since, energy remains conserved,
