Write the expression for the work done by an ideal gas in an isobaric process.

(N/A) An isobaric process is a thermodynamic process in which the pressure $P$ of the system remains constant.
For an ideal gas,the work done $W$ during a process is given by the integral $W = \int_{V_i}^{V_f} P \, dV$.
Since the pressure $P$ is constant in an isobaric process,it can be taken out of the integral:
$W = P \int_{V_i}^{V_f} dV$
$W = P(V_f - V_i)$
Using the ideal gas equation $PV = nRT$,we can also express this as:
$W = nR(T_f - T_i)$
where $n$ is the number of moles,$R$ is the universal gas constant,$V_i$ and $V_f$ are the initial and final volumes,and $T_i$ and $T_f$ are the initial and final temperatures.
