solid- molecules are close together and vibrating

liquid - molecules are loser, faster moving and take the shape of its container

gas- fast moving molecules and take whatever shape they want (like a room or the air outside)

Explanation:

Solids: The inter-molecular attraction force is the highest and the inter-molecular distance is the least. Solids have definite shape and volume.

Liquids: The inter-molecular attraction force is less than that of solids and the inter-molecular distance is more than solids. Liquids have definite volume but no definite shape.

Gases: The inter-molecular attraction force is the least and the inter-molecular distance is the highest. Gases have no definite shape or volume.
