Vedclass · Answer

(C) In an isobaric process,the pressure remains constant. According to the first law of thermodynamics,$\Delta Q = \Delta U + \Delta W$. When heat $\Delta Q$ is supplied to the gas,it expands against the external pressure,so work $\Delta W = P \Delta V$ is done by the gas. Simultaneously,the temperature of the gas increases,which leads to an increase in the internal energy $\Delta U$ of the gas. Therefore,both work is done by the gas and the internal energy of the gas increases.
