Final answer:
The false statement is that the weight of matter remains constant wherever it is located. Weight varies with gravity, but mass remains constant regardless of location.
Step-by-step explanation:
The statement that is FALSE among the given options is: C. The weight of matter remains constant wherever it is located. This statement is false because weight is a measure of the force of gravity on an object, which can vary depending on the location. For instance, an object on the moon weighs less than it does on Earth due to the moon's weaker gravitational pull. Nevertheless, D. The mass of matter remains constant wherever it is located is a true statement because mass is a measure of the amount of matter in an object and does not change regardless of its location in the universe.
Matter indeed exists in three states: solid, liquid, and gas. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.
