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 – ____ Lit. atm.
Answer: .
💡 Solution & Explanation
As isothermal U = 0 and process is irreversible Q = –W = – [– Pext (V2 – V1)] Q = 5 (20 – 60) = – 200 atm-L
