SOLAR SYSTEM

Detailed explanation-1: -A gas is a substance that is in a gaseous, or vaporous, state of matter. The term gas is also used in reference to the state itself when applied to matter that has the properties of a gaseous substance. Gas is one of four natural states of matter, along with liquid, solid and plasma. A gas has no fixed shape or volume.

Detailed explanation-2: -Common examples of gases include things like oxygen, carbon dioxide, nitrogen, hydrogen, helium, steam, and dry ice. Gasses are considered to be far less dense than solids or liquids because the particles in them are much more spread out.

Detailed explanation-3: -Liquids have no definite shape but have definite volume while gases have neither definite shape nor definite volume.So krypton, oxygen are gases, while carbon steel is solid. Kerosene is the only liquid.

Detailed explanation-4: -Deposition is when a substance in gas form changes states to become a solid. The gaseous substance gets deposited (usually as crystals) bypassing the intermediate liquid state. An example of deposition is when water vapor in the atmosphere changes directly into ice, such as the formation of frost.

Detailed explanation-5: -Therefore, among the given options, Kerosene is the only liquid and it has no fixed shape but has fixed volume.
