1.	A system absorbed 650 joule heat and did the work. Its internal energy change is 440 joules, then find out how much work has been done.
Answer» W = 210 JExplanation:We have been GIVEN SYSTEM absorbed heat Q = 650 Internal energy Δ U = 440 J Now We know that The change in internal energy of a system is equal to the heat added to the system minus the work DONE by the system.We know that Δ U = Q - W 440 = 650 - WW = 650 - 440W = 210 J Work has been done W = 210 J
