![]() For example, iron, gold, wood, sugar, etc. ![]() We can say that a substance with fixed volume and shape is called a solid. In this state of matter, a substance possesses definite volume and a definite shape. The three physical states of matter are described below States of Matter I Physical forms i) Solids Each state has its own unique physical properties. So, physically matter exists in three different states in nature. For example, the things that we see around us exist in three different states such as chair is in the solid-state, the water in a glass is in the liquid state and the oxygen that we inhale is present in the gaseous state. It means based on the physical state or properties under normal conditions of temperature and pressure, we can classify the matter into three states which are solids, liquids and gases. Physical classification of matter (Physical Forms) There are 118 elements out of which 92 elements are found naturally and the rest of the elements are created in laboratories and they are unstable. For example, a bar of the gold element is made of gold atoms (particles). ![]() The constituting particles of a particular matter have specific chemical and physical properties, so they cannot be broken down into any other substance. So, we can say that everything in the universe that has mass and occupies space and the presence of which can be felt by any of our senses is matter.Ī matter consists of particles such as atoms or elements. So, as per the definition of matter, light, heat, and radiations are not matter. ![]() Matter is anything that has mass and occupies space such as atoms, protons, compounds, tree, house, table, computer, etc. Next → ← prev What is matter | States of Matter | Classification of Matter ![]()
