(a) 2 kg of steam at 100 bar and 375°C expands reversibly in a perfectly
thermally insulated cylinder behind a piston until pressure is 38 bar and the
steam is then saturated. Use the steam tables to evaluate enthalpy, internal
energy and volume of steam at
(i) Start point
(ii) End point
(iii) What kind of process has taken place? Explain.
(iv)Calculate the work done by the steam and Heat transfer during the
process
