Question
What is the Bulk modulus for a perfect rigid body?
✓
Answer
Bulk Modulus $=\frac{-\text{p(V)}}{\Delta\text{V}}$ as the perfect rigid body does not change it's shape even at infinite (deforming a stretching) force. Hence, $\Delta\text{V}=0$ $\Rightarrow\ \text{B}=\frac{\text{pV}}{\Delta\text{V}}=\frac{\text{pV}}{0}=\propto$ So the bulk modulus is infinity.
