As we learnt

Bulk Modulus of elasticity in the isobaric process -

W = \int P\: dV

=P\left ( V_{f}-V_{i} \right )
 

- wherein

W =P\left ( V_{f}-V_{i} \right )

=nR\left ( T_{f}-T_{i} \right )

The bulk modulus of elasticity 

 K=\frac{\Delta P}{-\frac{\Delta V}{V}}

as \Delta P=0\: \: for\: \: isobaric\: \: process

so

 K=\frac{0}{-\frac{\Delta V}{V}}= 0
