Correct option is A

m = 2.0 × 10–2 kgΔT =45°CN2 is diatomic gas.Molar mass, M = 28gm = 28 × 10–3kg, Cp = 7/2 RR = 8.3J/mol-KHeat supplied, Q = nCpΔTn = number of moles = = 933 Joule.

Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at temperature $T_{o}$ , while Box B contains one mole of helium at temperature (7/3) T₀. The boxes are then put into thermal contact with each other and heat flows between them until the gases reach a common final temperature (ignore the heat capacity of boxes). Then, the final temperature of the gases T₁ , in terms of T₀ is
