Hey mate..☺️❤️
********. Answer.********
Matter – is anything that occupies space and has mass. Matter exists in three states namely; solid, liquid and gas.We know that matter comprises of particles. These particles are atoms and molecules. In this section, we will cover the nature of matter. Based on its physical state, we can divide the nature of matter into three major categories.
the buildings, the bridges, the atomic particles are all matter. Even our DNA, the air, the molecules inside our bodies, everything is matter.
Experiment =
Aim: to demonstrate that matter is made up of smaller particles
Apparatus: Beakers, potassium permanganate crystals, water.
Nature of Matter
Solids: →→→
Solids are all those substances having their particles very close to each other. There exist strong intermolecular forces between these particles. The particles are firmly held in their positions. These particles have only vibratory motion. Solids have a definite shape and definite volume. Examples include Wood, iron, aluminium etc.
Liquids: →→→
Liquids comprise of all those substances with weak intermolecular forces. The particles are capable of minimum movement. They have a definite volume. However, they do not have a definite shape. They usually take the shape of the container in which we place them. Examples include water, milk, etc.
Gases:→→→→
Gases are those forms of matter having very weak forces between their molecules. Hence, in gases, the molecules are free to move. The distance between molecules is large as compared to solids and liquids. Gases have neither fixed shape nor a definite volume. They tend to completely occupy the container in which they are placed. E.g. air, oxygen, hydrogen, methane, etc.
