Question
![(a)
Using the Beattie-Bridgeman equation, determine the final pressure of carbon dioxide when it
is heated in a rigid tank from 50 kPa and 20°C to 200°C.
(b)
You have 5 kg of steam in a 0.8 m rigid tank at a pressure of 4 MPa. Determine the
temperature of the steam using the ideal gas equation and the van der Waals equation
(c)
As part of an experiment, you filled a weighted piston-cylinder device as shown in Figure 2 with
10 kg of Refrigerant-134a. At this stage, the volume occupied by the refrigerant is 0.8 m?. The
pressure gauge now indicates that the pressure of the refrigerant to be 240 KPa. You then
applied heat to the bottom of the piston-cylinder device until the temperature reached 30°C.
Calculate the initial temperature and the change in volumes of the R-134a due to the heating
process.
