Introduction:
Properties of matter are the characteristics that help us identify and describe different substances. Matter is anything that has mass and occupies space, and its properties explain how it looks, behaves, and changes under different conditions. These properties are broadly classified into physical properties, such as color, density, and melting point, and chemical properties, such as reactivity and flammability. Understanding the properties of matter is very important in science because it helps us compare materials, predict their behavior, and use them effectively in daily life, industry, and technology.
