Answer 2

Effect of pressure on compressibility

Explanation:

• When subjected to pressure, compressibility relates to how much a given volume of material shrinks.
• Atoms, ions, and molecules in a solid or liquid are incredibly close together. Because there isn't enough space between the particles, they can't pack together.
• Gases are more compressible than any other matter It is compressible because the majority of a gas's volume is made up of large amounts of empty space between the gas particles.
• At normal temperature and pressure, the average distance between gas molecules is around 10 times the diameter of the molecules themselves. When a gas is compressed, the particles are driven closer together.
• Compressed gases are used in a variety of situations. Compressed gas anaesthetic is commonly utilised when a patient is undergoing a major surgery.
• The employment of extremely hot flames generated by compressed acetylene and oxygen mixtures is required for welding. Many summer barbeque grills are powered by compressed propane. Pressure is affected by the container's capacity.
• When the volume of a container is lowered, the gas molecules have less space to move around. As a result, they'll hit the container's walls more often, increasing the pressure.
• The ratio of increased pressure to decreased volume is known as the bulk modulus of a material. The ratio of volume change to change in the amount of pressure is compressibility.
