Slide 1: Introduction Let's start by understanding what "matter" is. Matter is anything that has mass and takes up space. Imagine your favorite toys, water, and the air around you - they're all forms of matter! Slide 2: Solids: Think of your toys, books, and even ice cream! Solids have a fixed shape and volume. Slide 3:Liquids: Pour yourself a glass of juice. Liquids take the shape of their container but have a constant volume. Slide 4:Gases: Imagine the air you breathe or the helium in balloons. Gases have neither a fixed shape nor a fixed volume. Slide 5: Quick Recap

1. States of Matter and
Particles Theory
Basically there are 3 states of Matter
1. Solid 2. Liquid 3. Gas

2. Solid
Solid has a fixed shape and volume. Due to
its rigid nature, particles in solid can only
vibrate about their mean position and
cannot move. Force of attraction between
particles is adamant.

3. Liquid
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.

4. Gas
In gases, particles are far apart from each other. Force of attraction
between the particles is negligible, and they can move freely. Gases have
neither a fixed volume nor a fixed shape. The gaseous state has the
highest compressibility as compared to solids and liquids.
