What state of matter has a definite volume but no definite shape

Answer: Liquid state

Explanation:

There are three states of matter named as solid, liquid and gas.

Solids have fixed shape and fixed volume as the molecules are strongly bonded to each other.

Liquids have fixed volume but no fixed shape as the molecules are weakly bonded to each other.

Gases have neither fixed shaped nor fixed volume as the molecules are very weakly bonded to each other.

The state is liquid.
