Vedclass · Answer

(A) Yes,it is possible to increase the temperature of a gas without adding heat to it. According to the first law of thermodynamics,$\Delta Q = \Delta U + \Delta W$. If we perform adiabatic compression on the gas,then $\Delta Q = 0$. In this case,$\Delta U = -\Delta W$. Since work is done on the gas $(\Delta W < 0)$,the internal energy $\Delta U$ increases. Because the internal energy of an ideal gas is directly proportional to its temperature $(U \propto T)$,an increase in internal energy leads to an increase in the temperature of the gas.
