Estimate the change in enthalpy and entropy when liquid ammonia at 270 K is compressed from its saturation pressure of 387 kPa to 1200 kPa.

Estimate the change in enthalpy and entropy when liquid ammonia at 270 K is compressed from its saturation pressure of 387 kPa to 1200 kPa. For saturated liquid ammonia at 270 K,

V^l = 1.551 10^-3 m³kg¹ and = 2.095 10^-3 K¹

The change in enthalpy is Jkg¹.

The change in entropy is Jkg¹K¹.
