Isothermal process

Vedclass · Answer

(B) According to the first law of thermodynamics,the change in internal energy $du$ is given by $dq = dw + du$.For an isothermal process,the temperature remains constant $(dT = 0)$.Since the internal energy of an ideal gas depends only on its temperature,for an isothermal process,the change in internal energy $du = 0$.Substituting $du = 0$ into the first law equation,we get $dq = dw + 0$,which simplifies to $dq = dw$.Therefore,the condition $dw = dq$ holds good for an isothermal process.

The condition $dw = dq$ holds good in the following process:
