Asubstance is round in one container and has a volume of one liter. in a much larger container, the substance is rectangular but still has a volume of one liter.

what state of matter is the substance in?

Liquid

Explanation:

Solids do not change shape, so we know it's not a solid.

Gases take the shape of their container, but they also expand to the volume of the container.  The substance in this problem has the same volume in different size containers, so we know it's not a gas.
