What is Matter?
Anything that has mass and occupies space. Matter exists in four states: solid, liquid, gas, and plasma. Chemistry is the study of the properties and transformations of matter. All matter is composed of atoms, which are the building blocks of elements and compounds.

Anything that has mass and occupies space. Matter exists in four states: solid, liquid, gas, and plasma. Chemistry is the study of the properties and transformations of matter. All matter is composed of atoms, which are the building blocks of elements and compounds.
Understanding matter and its states is foundational to all of chemistry, physics, materials science, and engineering. The behaviour of matter under different conditions (temperature, pressure, electromagnetic fields) drives the design of materials, processes, and technologies.
No direct safety concern for the fundamental concept. The specific hazards of matter depend entirely on the composition and state: gaseous toxic substances, liquid corrosives, solid reactive metals, and plasma radiation present very different risks.
