WebStep 1: Given data. C p = ( 7 / 2) R C V = ( 5 / 2) R. Step 2: To calculate dU, dQ and dW. Since the gas is diatomic in nature and the process is isobaric in nature, we use the formula: dU = nC V dT dQ = nC p dT dW = P × dV dW = … WebMar 27, 2024 · Internal energy change is proportional to temperature variation ΔT and type of gas with the following equation: ΔU = Cv·n·ΔT, where Cv is molar heat capacity under constant volume. For an ideal gas, it takes values: 3/2·R for monoatomic gas; 5/2·R for diatomic gas; and; 3·R for gases with more complex molecules.
WebSummary. For an ideal gas, the molar capacity at constant pressure Cp C p is given by Cp = CV +R = dR/2+ R C p = C V + R = d R / 2 + R, where d is the number of degrees of freedom of each molecule/entity in the system. A real gas has a specific heat close to but a little bit higher than that of the corresponding ideal gas with Cp ≃CV +R.
