A system undergoes a process in which it gives up 900 J of heat and its internal energy decreases by 300 J. of the system and its surroundings, which one does work in this process?

Text Solution

Verified by Experts

Given, `DeltaU=-300J and q=-900J`
`thereforeDeltaU=q+w or, -300=-900+w or, w=+600J`
w is (+)ve. This means work is done on the systemm by the surroundings and the amount of work done is 600 J.
