- 1 kg of Air was heated at constant temperature from 0.03 m3 and 101 kPa to 0.01 m3. By how much did the internal energy change? Assume (cv = 0.7177 kJ/kg.K)This pV diagram shows two different thermodynamic processes undergoneby 0.40 mol of a monatomic gas (where y equals 1.67). Process A is adiabatic, and process B is shown by a straight line (the process is unknown). What is the TF for both processes? For each one of the processes, what are the changes in thermal energy, the heat transferred, and the work done on the gas?. A 2.50 mole sample of a perfect gas for which Cv,m = 3R/2 (assume constant over T-range) undergoes the following two-step process: (1) from an initial state of the gas described by T = 13 ºC and P = 1.75 x 105 Pa, the gas undergoes an isothermal expansion against a constant pressure of 3.75 x 104 Pa until the volume has doubled. (2) subsequently, the gas is cooled at constant volume. The temperature falls to -24ºC. Calculate q, w, ∆U, and ∆H for each step and for the overall process.

Initially, the piston rests on some stops, but it is possible for it to move within the cylinder without friction. To lift the piston and start such motion, an air pressure of 1400 kPa is required. Now, heat is transferred to the system so that the temperature of the air reaches to a final value of 300°C. Fig. Q7 A. Which statement is true?
