1. What is the fundamental properties?Possesses mass and occupies volume
2. What is the constituent particles?Composed of atoms, which are made of subatomic particles (protons, neutrons, electrons)
3. What is matter made of?Matter is made of atoms. Atoms are tiny groups of protons, neutrons, and electrons.
4. Why do solids keep their shape but liquids don't?In a solid, particles are locked in a fixed pattern, so it keeps its shape and volume. In a liquid, particles can slide past each other, so it takes the shape of its container.

Mass: A fundamental property of matter representing its resistance to acceleration and its gravitational attraction.
Volume: The amount of three-dimensional space occupied by a substance or object.
Atom: The basic unit of a chemical element, comprising a nucleus and orbiting electrons.
Quantum Mechanics: A fundamental theory in physics describing nature at the smallest scales of energy and matter.
