Constant volume cooling


Jun 2016
Hello everyone, I solved a question but having no answer sheet I am not completely sure if what I did is correct.

5 kg of CO2 at its critical state is placed in a perfectly rigid container, which is then cooled until the temperature is 260 K.
- What is the volume occupied by liquid at the end of the process?
- How much energy is transferred as heat in the process?

We are supplied with a table of properties of saturated CO2 as function of temperature. Including, specific liquid volume, specific vapor volume, specific liquid/vapor/liquidvapor enthalpy.
