WebFrom the ideal gas law, P V = nRT, we get for constant pressure d(P V) = P dV +V dP = P dV = nRdT . Substituting this in the previous equation gives C p dT = C V dT +nRdT . Dividing dT out, we get C P = C V +nR . For an ideal gas, the heat capacity at constant pressure is greater than that at constant volume by the amount nR. 2 WebJun 25, 2024 · And Cp = Cv + R is the relationship that connects these two. This signifies as said above Cp always exceeds Cv by an amount n R [ n is moles of gas and R is the universal gas constant.
WebQ: (c) An ideal monoatomic gas at 1 bar and 300 K is expanded adiabatically against a constant pressure… A: (iii) Given Cv=1.5R=3/2R Cp-Cv=R Cp=R+1.5R… Q: Three moles of … WebR=C p−C v. This is so because U depends on temperature only, and dU is the same for any dT , regardless of what caused the change. For an adiabatic process, Q = 0 , so dU = -W = -p dV = C v dT . From the ideal gas law, pV = RT (n= 1), p dV + V dp = R dT and we have that R = C p−C v . Solve any question of States Of Matter with:-.
