Question
Three moles of an ideal gas are compressed isothermally from 60 L to 20 L using constant pressure of 5 atm. Heat exchange Q for the compression is β ____ Lit. atm.
Answer: .
π‘ Solution & Explanation
As isothermal οU = 0 and process is irreversible Q = βW = β [β Pext (V2 β V1)] Q = 5 (20 β 60) = β 200 atm-L
