Question
Liquid ammonia at 270K is compressed from its saturation pressure of 381 kPa to 12,000 kPa. For saturated liquid ammonia at these conditions: V = 1.551 * 10-3 m³ kg B= 2.095 * 10-³ K-1 k = 4.53 * 10-5 bar -1 Assume the ammonia is an incompressible fluid. What is the change in enthalpy in J/mol? What is the change in entropy in J mol-K ? What is the temperature after compression in Kelvin?
