Change in pressure will only affect the substances which are in ____.
- A
Liquid state
- B
Solid state
- C
Plasma state
- D
Gaseous state
Changing the pressure of an equilibrium system in solid or liquid will have negligible effect but changing the pressure on an equilibrium system in which gas is involved will be a stress to the system .thus according to boyle's law , the volume of a given mass of a gas at constant temperature is inversely proportional to the pressure applied to the gass. PV=k.
a) Liquid state
In the liquid state, the molecules are relatively close together and have more intermolecular forces compared to gases. A change in pressure can affect the density and compressibility of liquids, but their volume and shape remain relatively constant under normal conditions.
b) Solid state
In the solid state, the particles are tightly packed and have strong intermolecular forces that hold them in a fixed position. Changes in pressure do not significantly affect the volume or shape of solids, as they are generally incompressible.
c) Plasma state
In the plasma state, the substance is ionized and consists of charged particles (ions and free electrons). Plasma is usually formed at very high temperatures and is not as common on Earth's surface. Changes in pressure can affect the behavior of plasmas in certain situations, but in most cases, they are not directly affected by pressure like gases.
d) Gaseous state
In the gaseous state, the particles are widely spaced, and they have weak intermolecular forces. Gases are highly compressible, and changes in pressure significantly impact their volume, density, and other properties. Boyle's law and Charles's law are examples of how pressure affects the volume and temperature of gases, respectively.
