When an ice is being heat up, it will undergo a series of thermodynamic process. Explain with a diagram that how ice will undergo latent heat of fusion, latent heat of vaporization and temperature changes under heat transfer process.

A piston-cylinder device contains air initially at 350 kPa, 650 K and 0.4 m3 undergoes a thermodynamic cycie as follows: 1 -2: A compression process from initiai volume ta 0.2 m3. This processfollows polytropic law, PV 1.25 constant. 2 -3: An isobaric expapsion process to 0.4 m3. 3 - 1: An isoihoric process to the initial pressure.   i) Determine the pressure at state 2 and 3kPa.ii) Calculate the mass of air, kg.iii) Sketch the cycle on a P-v diagram and label all pressures and volumes.iv) Calculate the temperatures at state 2 and 3, K.v) Determine the net work fcr the entire cycle, kJ.vi) Calcuiate the heat transfer for each process, kJ Assume air as an ideal gas, take R = 0.287 kJ/kg.K and Cv=0.718 kl/kg.K.
