The statement "The amount of matter in an object is its volume" is FALSE.
Explanation:
1. Volume: Volume refers to the amount of space an object occupies. It is a measure of how much three-dimensional space an object takes up. For example, a cup may have a certain volume that indicates the space it occupies.
2. Amount of Matter: The amount of matter in an object is actually referred to as its mass. Mass is a measure of the quantity of matter in an object, regardless of its volume or shape. For instance, a cup may have a specific mass that represents the amount of matter it contains.
In summary, volume and mass are two distinct properties of an object. Volume relates to the space an object occupies, while mass relates to the quantity of matter in an object. The amount of matter in an object is determined by its mass, not its volume.
