The matter in the air is what supports the enormous weight of a plane. Since there is almost no kinetic energy being transferred from one atom to another, the atoms begin to clump together. The 31-year-old shared a snap taken in her bathroom to her Instagram Stories on Friday. If unconfined, the particles of a gas will spread out indefinitely; if confined, the gas will expand to fill its container. In general, the matter has mass and occupies space.

For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). At the most fundamental level, matter is composed of elementary particles known as quarks and leptons (the class of elementary particles that includes electrons ).
