QUESTION 3 (a) Explain the following in simple terms of an ideal gas. (i) Difference between R dan R.. How those two related. (ii) Difference between mass and molar mass. How those two related. (b) A rigid tank contains 10 kg of steam at a pressure of 1.4 MPa and a temperature of 250°C as shown in Figure Q3(b). Now the steam is allowed to cool at constant volume until the temperature drops to 120°C. At the final state, determine (i) The pressure. (ii) The quality. (iii) The enthalpy.
