A matter is made up of tiny particles called atoms. There are three states of matter. Solid, liquid, and gas. For example, table, chair, air, water, honey, etc. Characteristics of the matter: The particles of matter have space between them. Particles of matter are continuously moving. Particles of matter attract to each other.
A physical property is an attribute of matter that is independent of its chemical composition. Density, colour, hardness, melting and boiling points, and electrical conductivity are all examples of physical properties. Any characteristic that can be measured, such as an object’s density, colour, mass, volume, length, malleability, melting ...
Liquid Definition. In a liquid state of matter, particles are less tightly packed as compared to solids. Liquids take the shape of the container in which they are kept. Liquids are difficult to compress as particles have less space between them to move. Liquids have fixed volume but no fixed shape.
Three States of Matter (Matter Definition) - Matter exists in three physical states: solids, liquid and gases. The classification of matter into solids, liquids and gases in termed physical classification of matter. The three states of matter are traditionally recognized in chemistry.

All materials contain matter, which is made of tiny particles called atoms. Matter is the substance that gives materials “mass”, which in turn will provide a force called “weight” under gravity. Another way of defining matter is any object that has mass and occupies space. For example, every person has mass, and occupies space, therefore it can be said that every person is made of matter.
CBSE Class 9 Science Notes Chapter 1 Matter In Our Surroundings. Download PDF. Anything that has mass and takes up space is referred to as matter. hydrogen and oxygen, sugar and sand, air and water, etc. Small, minuscule particles make up matter. Due to the space between them, matter particles are attracted to one another.
Particles of the matter show continuous random movements. The kinetic energy they possess helps them in this movement. The spreading of ink in a beaker of glass, the smell that comes from agarbattis, etc. are few illustrations that show the movement of particles of a substance. When the particles of two different types of matter intermix on ...
The postulates of the particle theory of matter are given as: 1. All matter is made up of tiny particles known as atoms. 2. Particles of matter are constantly in motion. 3. Particles of matter attract each other. 4. Particles of matter have spaces between them.
The matter is made up of substances which contain molecules. The molecules, in turn, are made up of groups of atoms. Atoms in simple terms are defined as the smallest unit of matter. In ancient times scientists wondered whether the matter could be further divided or not. Around 500 BC the idea of divisibility of matter evolved in India.
Which is the intensive property? An intensive property is a physical property of a system that does not depend on the system size or the amount of material in the system. According to the definitions, density, pressure and temperature are intensive properties and volume, internal energy are extensive properties. Q2.
