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. Kinetic Theory 14. THERMODYNAMICS 163 One way: We do some mechanical work, say 1 kJ, by rotating a set of small paddles and thereby chur ning water . From first law, dU = – dW, i.e., work done by the system is equal to decrease in internal energy. The graph drawn between the pressure p and the volume V of a given mass of a gas for an isothermal process is called isothermal curve and for an adiabatic process it is called adiabatic curve . In practical life thermal efficiency of a steam engine varies from 12% to 16%. Thus, if A and B are separately in equilibrium with C, that is if TA = TC and TB = TC, then this implies that TA = TB i.e., the systems A and B are also in thermal equilibrium. e.g., petrol and diesel engine. where Q2 is heat absorbed from the sink, Q1 is heat rejected to source and T1 and T2 are (i) Isothermal Process A process taking place in a thermodynamic system at constant temperature is called an isothermal process.
