Question

how does compressibility help to account for nature of gas

Answer 1

The compressibility factor (Z) is a useful thermodynamic property for modifying the ideal gas law to account for behavior of real gases. It is a measure of how much the thermodynamic properties of a real gas deviate from those expected of an ideal gas.

Answer 2

● Compressibility means how much you can pressurise a substance.
Due to compression, we need force which creates a area developing pressure.

● It helps to account for the nature of a gas because the gases have large inter molecular spaces between their molecules and, hence gases can be highly compressed.
