Atmospheric pressure is 100 kPa in a system of cylinders and pistons.The mass of the piston is 4 kg and the area of the piston is 4.0 cm2. The following process takes place by external heat transfer. (Gravity acceleration is 10 m / s2).
1. Calculate the pressure inside the cylinder in kPa.
2. The cylinder contains 0.1 kg of water vapor, and the temperature of the water vapor is 150oC. Find the volume and internal energy of water vapor in the initial state.
3. When the energy is applied by heat transfer and the piston moves freely to a final volume of 0.29376 m3, find the work done externally by the piston in kJ.
4. Find the final temperature.
5. During the process, find the heat transfer in kJ.
