Question

16 g of oxygen at 37°C is mixed with 14 g of nitrogen at 27°C. Find the temperature of the mixture?

G1 Physics · Accepted Answer

Use PV=nRT, U=(f/2)nRT, γ=1+2/f and vᵣₘₛ=√(3RT/M). At the same temperature, average translational kinetic energy depends only on T. Substituting the given values gives 32.
