CO₂ is sold commercially in steel containers at 60 bar. The gas is leaking through the outlet valve slowly so that the temperature may be assumed constant at the oom temperature of 300 K. (a) What is the work done in the expansion of 10 kg of this gas from 60 bar to 1 bar? (b) If the temperature were constant at 290 K, would there be any difference in the work done? (c) What are the changes in enthalpy in both the above cases?

Question
Please show detailed solution Answer key (a) 2282 kJ (b) 2206 kJ (c) 0 CO2 is sold commercially in steel containers at 60 bar. The gas is leaking through the outlet valve slowly so that the temperature may be assumed constant at the room temperature of 300 K. (a) What is the work done in the expansion of 10 kg of this gas from 60 bar to 1 bar? (b) If the temperature were constant at 290 K, would there be any difference in the work done? (c) What are the changes in enthalpy in both the above cases?
