Compressibility is the measure of how much the volume of a substance decreases under pressure. - Solids: Particles are tightly packed and held in fixed positions. They are very difficult to compress. - Liquids: Particles are close together but can move past each other. They are only slightly compressible, much less so than gases. - Gases: Particles are far apart and move randomly. There are large spaces between particles, making them highly compressible. Therefore, the order of increasing compressibility is Solid
Matter around us can exist in three different states, namely, solid, liquid and gas. The correct order of their compressibility is
