WebThe internal combustion engine is an example of a heat engine. In this case, the internal energy stored in the chemical (gasoline) is converted to thermal energy (the flow of heat) that results in the performance of work. Heat engines will be discussed in greater detail in the Thermodynamics chapter of The Physics Classroom Tutorial. 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. Δ U = Q − W. 12.6. Here, Δ U is the change in internal energy, U, of the system.
