Final answer:
True, Matter is defined as anything that occupies space and has mass. Solids, liquids, and gases are all examples of matter.
Step-by-step explanation:
True. Matter is indeed the substance that makes up all material in the universe. It has mass, occupies space, and is composed of fundamental particles called atoms. These atoms can combine to form molecules, and the arrangement and motion of these particles determine the physical state of matter. The three primary states of matter are solid, liquid, and gas. In a solid, particles are tightly packed and vibrate in fixed positions. In a liquid, particles are more loosely packed and can move past each other. In a gas, particles have greater freedom of motion and are farther apart. These states can undergo phase transitions under different conditions.
