Matter can be defined as anything that has mass and takes up space. It is the physical substance that makes up everything in the universe, including the air we breathe, the water we drink, the food we eat, and even the clothes we wear.
Matter can exist in three states – solid, liquid, and gas – based on the arrangement of its particles and the amount of energy they possess. These particles include atoms, molecules, and ions, and they are constantly in motion, interacting with each other and their surroundings. Understanding the properties and behaviour of matter is essential to many areas of science and technology, including chemistry, physics, and engineering.
The three states of matter are solid, liquid, and gas:
A solid is a state of matter in which the molecules are tightly packed together and have a fixed shape and volume.
Ice, Brick, Ball etc.
A liquid is a state of matter in which the molecules are closed together but not tightly packed, and have a fixed volume but not a fixed shape.
Water, Milk, Gasoline etc.
A gas is a state of matter in which the molecules are widely spread out and have neither a fixed shape nor a fixed volume.
Air, Helium, Carbon Dioxide etc.
