How do scientists define matter? (please write a simple definition but not too simple like not really explain like it has this it does this or like yeah)

Matter is anything that has mass and takes up space (has volume)

Explanation:

Matter is composed of atoms containing protons, neutrons, and electrons. Matter has physical and chemical properties, such as boiling point (physical) and flammability (chemical). hope this helps:)

In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.
