Sample problem of first law of thermodynamics

WebThe first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is Δ U = Q − W. 15.1 Here Δ U is the change in internal energy U of the system. WebThe first law of thermodynamics states that the change in internal energy of a closed system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is 12.6 Δ U = Q − W. Here, Δ U is the change in internal energy, U, of the system.

WebThe first law is a statement of energy conservation. It tells us that a system can exchange energy with its surroundings by the transmission of heat and by the performance of work. The net energy exchanged is then equal to the change in the total mechanical energy of the molecules of the system (i.e., the system’s internal energy).
