Answer:
It has indefinite shape but definite volume
Explanation:
Matter generally means any material/substance that has mass and occupies space. There are three states of matter; solid, liquid and gas.
A solid matter has a definite shape and hence cannot be determined by the wall of the its container. Solid matter is not measured in volume, instead it is measured in mass.
Liquid and gaseous matter have some similar physical properties as they both have indefinite shape but definite volume. Having indefinite shape means there shape is determined by the container in which they are stored. For instance, water will assume a cylindrical shape when placed in a cylindrical container but the same water will assume a conical shape when poured in a conical container. Using this same example, the volume of water would not change despite been transferred from one container to another container which explains its definite volume.
Hence, liquid state of matter has indefinite shape but definite volume.
