Question

why liquids are considered “incompressible,” while gasses and solids can be compressed?

In: Physics

Answer 1

Liquids can be compressed, generally easier than solids. It’s just it’s a common assumption to make calculations with liquids easier because the error is pretty small. We generally often assume solids are incompressible when working with lower pressures.
