Explain the following:
Gases have no definite shape nor a definite volume of their own.

Liquids have no definite volume.

Liquids have no definite ____

Solids have a definite volume and a definite shape.

Why solids have definite shape and volume ?

Why do solids have a definite volume?

Why do solids have a definite volume?

Out of three states of matter, only the gases have most of the physical properties common. They have neither definite shapes nor definite volume. In addition to this, the gases obey different gas laws such as Boyles's law. Charles law, Dalton's law of partial pressures etc. Based upon these gas laws, ideal gas equation PV = nRT has been derived. Answer the following questions on the basis of above paragraph. (i) what is Dalton's law of partial pressures ? (ii) Derive ideal gas equation on the basis of all gas laws.

Why do solids have a definite shape and volume but not gases?

Which of the following has definite length?

Matter with no fixed shape but definite volume exists in following state.
