Understanding Matter: Properties and Changes in Chemistry

Matter is anything that occupies space and has mass, composed of atoms that move due to kinetic energy. Examples include everyday objects like books, desks, and people, while non-examples are light, sound, thoughts, and emotions. This article explores the physical and chemical properties of matter—characteristics that can be observed without altering the substance, such as texture, color, and melting point, as well as its ability to undergo changes, including flammability and reactivity. Join us in exploring the fascinating world of chemistry!
