Solids and Liquids

[Jessica Tsui 1H]

In reactions with solids and liquids, why is PV insignificant?

[Riya Shah 4H]

Because solids and liquids can be called 'incompressible'. It means that their volume varies very little or not at all with change in pressure.

[Carine Tamamian 2B]

Solids and liquids don't count because their pressure and volume aren't affected

[Calvin Patel 2H]

It is because you cannot compress a solid or liquid like you can to a gas. So therefore, the pressure and change in volume are negated since it won't make a difference.

[Michael Novelo 4G]

when a solid becomes a liquid or vice versa the volume isn't really changed. When a solid or liquid becomes a gas then there is a change in volume because the gas wants to expand it has different characteristics compared to a solid or liquid.

Solids and liquids have a constant volume. Also, pressure is really only used to describe gasses.
