It sounds like you are studying liquids, solids and gases.
A liquid doesn't have a definite shape; it will shape like any container you pour it in.
A gas doesn't have a definite volume; you can keep it at high pressure or low pressure and it will squeeze.
A solid is the third type of physical state.
A solid has a fixed volume and a fixed shape.
Solid
solids
A liquid has a fixed volume but not a fixed shape. If you put it into a graduated cylinder, it will take the shape of the cylinder. If you put it into a bowl, it will take the shape of the bowl.
It has a fixed shape and volume
Solids are substances which have a fixed volume and fixed shape. Liquids, on the other hand, have a fixed volume but no definite shape. Finally, gases don't have a definite volume or shape.
Gas has an indefinite shape or volume. Liquid has a fixed shape and volume. Solid has a fixed shape and volume.
A liquid has a constant volume but no fixed shape.

A solid is a substance that has a fixed volume and a fixed shape, and a liquid has a fixed volume but not a fixed shape, and a gas has no fixed volume or shape.

a liquid
A gas is a substance with no definite shape or volume.
A liquid
A substance which has no fixed shape, but takes on the shape of its container, and has a fixed volume at a fixed temperature. It is not compressible.
A SOLID. They have a fixed volume mass and shape because the particles are so closely packed together.
