Basic Chemistry Guide For Learning Chemistry

Introduction

Everything found in this universe is made up of some materials, scientists have named them as For example, the food we eat, the air we breathe, stones, clouds, stars, plants, animals, water, dust, everything is categorized as matter

Characteristics of Particles of Matter

Particles of matter are very small, normally, not visible from naked eye. Particles Of Matter

Kinetic energy of particles directly depends on the temperature, as temperature increases, the speed of the movement also increases. The particles of matter have attracting force; therefore, they attract each other. The attracting force of the particles keeps the particles together; however, the strength of the attracting force varies from one kind of matter to another

All the solid materials have a definite shape, distinct boundaries, and fixed volumes. Most of the solid materials have negligible compressibility. All the solid materials have a natural tendency to maintain their shape when subjected to outside force. The solid materials can be broken under applied force, but it is very difficult to change their shape, as they are rigid.

Unlike solids, liquids have no fixed shape; however, they have a fixed volume

Liquids take up the shape of the container in which they are kept

Liquids have the property to flow and change shape

Gaseous State

Matter in the form of air, which is neither solid nor liquid, is known as gas. For example, oxygen, nitrogen, hydrogen, etc

Unlike solid, gas has not definite size and shape

The gases, such as liquefied petroleum gas (LPG used in cooking); compressed natural gas (CNG used as fuel in vehicles), etc. have high compressibility; therefore, large volume of a gas can be compressed into a small cylinder and can be transported easily
