A substance in the solid phase (state) of matter has a definite shape and a definite volume.

What is volume?

Volume is the amount of space taken up by an object, while capacity is the measure of an object's ability to hold a substance, like a solid, a liquid or a gas. Volume is measured in cubic units, while capacity can be measured in almost every other unit, including litres, gallons, pounds, etc.
