Matter is all around us. It can be classified based on different properties. For example, river water is moving matter, but, the mountain is non-moving matter. The fish is living matter, but, the factory by the river is non-living matter. The trees are visible matter, but, the air that makes them move is invisible matter.
We have classified matter based on whether it moves, whether it is living, and whether it is visible. Are there other properties based on which we can classify matter?
