Q10) Two containers thermally isolated from the environment contain the same amount of nitrogen gas. They are initially connected with a closed valve. If T-T2 (temperatures of the containers), (a) Explain why the temperature will remain constant after the valve is opened. (b) Find the final pressure in terms of P and P (Initial pressures) after the valve is opened (do not K P V T include other parameters in your answer). P2 V2 T 3R 2 is the universal gas constant. Q12)Prove that Cp Cy = R for any ideal gas, where Cp is molar specific heat at constant pressure, Cy is molar specific heat at constant volume and R is the universal gas constant. = Q13)Prove that in a reversible adiabatic process PVY is constant where P is pressure and V is volume and y Cp is molar specific heat at constant pressure, Cy is molar specific heat at constant volume. Cp Cv' Q11) Prove that Cy = for a monatomic ideal gas, where Cy is molar specific heat at constant volume and R
