Cv of a diatomic gas
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. WebApr 20, 2024 · Sorted by: 3. Once the gases are mixed and at same temperature, ( n 1 + n 2) C v ¯ T = n 1 C v 1 T + n 2 C v 2 T. Cancelling temperatures, ( n 1 + n 2) C v ¯ = n 1 C v 1 + n 2 C v 2. where C v ¯ is the molar average heat capacity at constant volume of the mixture. So. C v ¯ = x 1 C v 1 + x 2 C v 2.
