POWER POINT PRESENTATION TOPIC: STATES OF MATTER Solids, liquids, & Gases IDENTITY NAME: SHRADDHA CLASS: IX(B) Roll no: 40 SCHOOL: BHAURAV DEVRAS SARASWATI VIDYA MANDIR DATE: 15-06-2024

MATTER Definition : Anything which occupies space and has mass is called matter. E.g. Pen, Paper, Milk & Air are the example of matter Matter is made up of particles which are in continual random motion. All the things which we come across in daily life are composed of matter. Based on the discovery of electrons, protons and neutrons, hydrogen and helium are found to exist which are primary gases and are also considered as matter.

THE CHARACTERISTICS OF MATTER The characteristics of matter are as follows: Matter is composed of particles. The particles of matter have void space in between them. The particle of matter is very small in size and occupies mass. The particles are in a state of random motion and possess kinetic energy. The particles of matter attract each other forces of attraction.

States of Matter: One of the forms that matter takes, such a solid, liquid or gas.

Solid Tightly packed Liquid closely packed Gas loosely packed Solids: A state of matter where the particles only vibrate and cannot move from their position Liquids: A state of matter where the particles move enough to slide past each other Gases: A state of matter where the particles bounce freely and rapidly

SOLID When particles are arranged and packed closely –compare to those in a gas or liquid -- and are relatively stable, they are considered to be in a solid state. Solids tend to have a rigid shape. The particles of a solid only vibrate about their fixed positions. The particles of a solid have the minimum kinetic energy. Due to this, Solids have the most orderly arrangement of particles.

THE CHARACTERISTICS OF SOLIDS Solids have fixed shape, volume & mass. Solids cannot be compressed much. Solids have high densities. They are heavy. Solids do not fill their container completely. Solid do not flow. Like Table, shoes, bricks, stones etc.

LIQUID When particles are arranged loosely packed –compare to those in a solids -- and are not relatively stable, they are considered to be in a liquid state. Liquid tend to have undefined shape. The particles of a liquids also vibrate about their fixed positions. The particles of liquids have more kinetic energy than the particles of solid. Its particles are able to slide over one another due to slightly weaker interparticle forces of attraction.

Liquids have the fixed volume & mass but to definite shape. Like solids, liquids cannot be compressed much. Liquids have moderate to high densities. They are usually less dense than solids. Liquids do not fill their container completely. Liquids generally flow easily. Like juices, water, oil, petrol etc. THE CHARACTERICS OF LIQUIDS

GAS When particles are farther apart from one another –compare to those in solids & liquids -- and the spaces between the particles of gas is very large, they are considered to be in a gas state. Gas tend to have undefined shape & volume. The particles of gases are free to move in any direction. The particles of gas have maximum kinetic energy than the particles of solid & liquid. Due to this, The particles of gas move with high speeds in all directions .

THE CHARACTERISTICS OF GAS Gases have no fixed shade & volume but have fixed mass. Gases can compressed easily. Gases have very low densities. They are very, very, light. Gases can fill their container completely. Gases flow easily. Like air, stream, smoke, nitrogen etc.
