This state of matter has a volume but no definite shape. Particles are not tightly packed together and although there is free movement within the volume, they are incompressible.

Which one of the following states of matter does this statement best describe?

(Please select 1 option)

Liquid Correct

Gas

Vapour

Plasma

Solid

Explanation

Solids have a definite volume and shape. Particles are packed closely together and are incompressible. There is enough thermal energy to produce vibration of particles within the tight lattice.

Liquids have a volume but no definite shape. Particles are less tightly packed together and although there is free movement within the volume, they are incompressible.

Gases have no finite shape or volume. Particles are free to move rapidly in a state of random motion. They are compressible and shaped completely by the space in which they are held. Vapours exist as a gas phase in equilibrium with identical liquid or solid matter below its boiling point.

Plasma is the most prevalent state of matter in the universe, formed by heating atoms to very high temperatures to form ions.
