Select which of the following characteristics match with the correct state of matter.
Tasya [4]

The gases have no definite shape, low density, and are highly compressible while the liquids only have a definite volume but no definite shape.

<h3>What is a Matter?</h3>

Any substance which has mass and occupies space is called matter. Commonly, there are three states of matter that are:

  • Solid - Solids have a rigid shape, definite volume, and high density.
  • Liquid - Liquids have definite volume but no definite shape. They take the shape of the container in which they are placed.
  • Gas - Gases have neither definite shape nor definite volume and have low density. They completely occupy the container in which they are placed.

There are other two states of matter that are Plasma and man-made Bose-Einstein condensates. They are not so common.

Plasma is commonly found in the universe. Stars are the superheated balls of the plasma.

Thus, gases have no definite shape, low density, and are highly compressible. On the other hand, the liquids only have a definite volume but no definite shape.
