Option
A.2
B.4
C.3
D.2.5

Answer 1

One of the four basic states of matter is gas (the others being solid, liquid, and plasma). A pure gas can be made up of individual atoms (such as a noble gas like neon), elemental molecules (such as oxygen), or complex molecules (composed of a variety of atoms) (e.g. carbon dioxide).

Complete answer:
Compressibility refers to how much a particular volume of stuff shrinks when subjected to pressure. When we apply pressure to a solid or a liquid, the volume of the object does not change much. The solid or liquid atoms, ions, or molecules are very close together. The individual particles cannot pack together because there is no room between them. Gases are more compressible than liquids or solids, according to the kinetic-molecular hypothesis. The non-compressible volume of a gas is 2 times the actual volume of gas molecules. Because the majority of a gas's volume is made up of enormous quantities of empty space between the gas particles, gases are compressible. The average distance between gas molecules at normal temperature and normal pressure is around 10 times the diameter of the molecules themselves. The gas particles are driven closer together when a gas is compressed, such as when a scuba tank is full. Compressed gases are employed in a wide range of applications. Patients with damaged lungs are frequently given oxygen in hospitals to help them breathe better. When a patient is having a major procedure, compressed gas anaesthesia is usually used. Welding necessitates the use of extremely hot flames generated by compressed acetylene and oxygen mixtures.

Note:
An English scientist named Robert Boyle (1627-1691) is often regarded as one of the forefathers of modern experimental chemistry. He observed that increasing the pressure of an enclosed sample of gas while maintaining the same temperature reduced the volume of the gas by half. When the temperature is held constant, Boyle's law asserts that the volume of a given amount of gas varies inversely with the pressure. This is how an inverse connection is described. The value of one variable drops as the value of the other rises.
