850 g of a certain substance is heated at constant pressure from 40 ⁰C to 70 ⁰C. Specific heat capacity at constant pressure is given by the following expression:
8Cp² - 5Cp = 7
Where:
Cp = specific heat capacity at constant pressure in kJ/kg-K
Determine the change in entropy in J/K.
A piston-cylinder assembly contains 20 kg of ammonia, initially at 80 kPa and -10°C. The ammonia is compressed to a pressure of 550
kPa. During the process, the pressure and specific volume are related by po¹¹ = constant. Determine the work and the heat transfer,
in kJ.
Determine work
Work can be evaluated:
as equal to the pressure times (final specific volume minus initial specific volume).
O by integrating volume from the initial pressure to the final pressure.
O as equal to the pressure times (initial volume minus final volume).
as the integral of pdV from the initial volume to the final volume.
