Given that for the gas Ar the heat capacity C₁ = (3R/2) = 12.47 J/K/mol, calculate the velocity of sound in Ar at T = 298 K using the ideal-gas relation between Cp and C,. Do the same for N₂, for which C, = 20.74 J/K/mol. For nitrogen at p = 1 atm, and T = 298 K, calculate the change in temperature when it undergoes an adiabatic compression to a pressure of 1.5 atm. y = 1.404 for nitrogen.
