Class 11 Physics Thermodynamics: Introduction: Introduction . Heat given to a thermodynamic system (ΔQ) is partially utilized in doing work (ΔW) against the surrounding and the remaining part increases the internal energy (ΔU) of the system. In adiabatic process, if gas expands, its internal energy and hence, temperature decreases and vice-versa. (iii) Isolated System It exchanges neither energy nor matter with the surrounding. It is impossible to obtain a continuous supply of work from a body by cooling it to a temperature below the coldest of its surroundings. List Of Physics Formulas Class 11 Chapter Work Energy Power.
