(a) Calculate the change in entropy when a 0.125-kg chunk of ice melts at 0 °C. Assume the melting occurs reversibly.

(I) 1.0 kg of water is heated from 0°C to 100°C. Estimatethe change in entropy of the water

(i)     Define the term entropy in thermodynamics. (ii)    In what way entropy is related to third law of thermodynamics? Compare and contrast adiabatic processes and Cyclical processes in thermodynamics with necessary explanations and sketches. Let 1.00 kg of liquid water at 100°C be converted to steam at a pressure of 1.01 * 105 Pa. The volume of water changes from an initial value of 1.00 * 10-3 m3 as a liquid to 1.671 m3 as steam. The heat of vaporization is 2256 kJ/kg. (i)               How much work is done by the system during the process? (ii)              How much energy is transferred as heat? (iii)            What is the change in the system’s energy during the process?
