Problem- a refrigeration system involves the expansion of a, Ask an Expert

Academics

Problem- A refrigeration system involves the expansion of a compressed gas to 1.0 atm. Two gases, He (monatomic) and N2(diatomic) are available. The system containing the expansion can be considered adiabatic, the behaviour of the gases ideal and the path as a reversible one. The temperature in the initial (compressed state) is 300 K and the final temperature required is 185 K. Calculate the pressures required in the initial states for each of the gases He and N2.
