Question

One hundred cubic meters of carbon dioxide initially at 150 degrees Celsius and 50 bar is to be isothermally compressed in a frictionless piston-and-cylinder device to a final pressure of 300 bar. Assume that this is a reversible process.

a.)

Use the ideal gas equation of state to calculate:

i. The volume of the compressed gas

ii. The work done to compress the gas

iii. The heat flow on compression

b.)

Use the van der Waals equation of state to calculate:

i. The volume of the compressed gas

ii. The work done to compress the gas

iii. The heat flow on compression

Answer to part b should be:

Q = -1,407,000kJ and W = +855,000 kJ

Answer 1

Solution Given also given that Co2 is an ideal gas since the potess is the sotbesma pyocess So bal xloom O-0821 300 ×0.986 Volume of the lernpressed gas (%)- 16-66m3
