Overview
Compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change. It is the reciprocal of the bulk modulus.
💡
Pro Tips
Ensure both volumes are in the same units.
Ensure both pressures are in the same units.
Compressibility is usually very small for liquids and solids compared to gases.

Fun Facts
"Water is only slightly compressible; at the bottom of the ocean, it's compressed by only about 1.8%."
"Gases are highly compressible because of the large empty spaces between molecules."
"The bulk modulus is used to describe how resistant a substance is to compression."
