Mr Zahin is conducting an experiment to understand the energy interaction when a system is undergoing a heating process. In his methodology, he constructed a closed system that holds water in two forms: liquid and vapour. Each of the water forms weight for 1kg. The initial pressure of the system is recorded at 700kPa. Zahin then supplied heat to the mixture at constant pressure, until the temperature reaches 350C. As a junior scientist who reports directly to Mr Zahin, you were requested to help him with the findings. a. Illustrate the closed system, showing the system's boundary and all the energy interactions. [3 marks] b. Calculate the specific volume and specific internal energy of the water before and after the heating process. [12 marks] c. Determine the specific work and specific heat during the heating process. [4 marks] d. Sketch the Tv and the Pv diagrams for the process indicating the path and direction of the processes. [6 marks]
