What is matter Class 9 Question Answer?Matter is anything that has mass and occupies space. The mass of an object is a measure of the amount of matter in the object. The amount of space an object occupies is its volume. The SI unit of mass is the kilogram (kg). The SI unit of volume is the cubic metre (m3).

Matter can be classified into three states: solid, liquid, and gas. The state of a substance depends on the forces between the particles that make up the substance.

In a solid, the particles are closely packed together and are held in place by strong forces between the particles. The particles in a solid are not free to move around.

In a liquid, the particles are close together but are free to move around. The forces between the particles are not as strong as in a solid.

In a gas, the particles are far apart and are free to move around. The forces between the particles are very weak.

Matter is anything that has mass and occupies space. It is the stuff that makes up the universe. Everything that you can see and touch is matter. Even the air that you breathe is matter.

Matter is made up of tiny particles. The nature of these particles determines the properties of matter. For example, the particles of a solid are closely packed together, while the particles of a gas are spread out. The different states of matter are solid, liquid, and gas.

solids have a definite shape and volume
liquids have a definite volume but no definite shape
gases have neither a definite shape nor volume

The physical and chemical properties of matter are determined by the way the particles are arranged and how they interact with each other. For example, the boiling point of a substance is determined by the forces that hold the particles together.

Matter is anything that has mass and occupies space. It is the physical substance of which the Universe is made.

In class 9, we learn about the different states of matter - solid, liquid and gas. We also learn about the changes of state - melting, freezing, vaporisation and condensation.
