Introduction to Chemistry

Chemistry is the branch of science that studies the composition, structure, properties, and changes of matter. It plays a crucial role in understanding the world around us, from the air we breathe to the food we eat and the medicines we take. Chemistry helps us explore how substances interact, transform, and contribute to various processes in nature and industry. Explore

Why is Chemistry Important?

Chemistry is often called the "Central Science" because it connects physics, biology, environmental science, and engineering. Some key areas where chemistry is essential include:

Chemistry in Everyday Life

Chemistry is all around us! Some everyday examples include:

Studying chemistry helps us understand how matter interacts, leading to innovations in science and technology that improve our lives. Whether in the lab or in daily experiences, chemistry is a fascinating subject that shapes the world we live in!

Chemistry is the branch of science that studies matter, its composition, structure, properties, and the reactions it undergoes. It connects with physics, biology, and environmental sciences.

Chemistry is divided into five main branches:
  • Organic Chemistry – Study of carbon-containing compounds.
  • Inorganic Chemistry – Study of non-carbon elements and compounds.
  • Physical Chemistry – Study of physical properties and behavior of chemical substances.
  • Analytical Chemistry – Techniques for identifying and quantifying matter.
  • Biochemistry – Study of chemical processes in living organisms.

Chemistry is involved in:
  • Cooking and food preservation.
  • Medicines and healthcare.
  • Cleaning products like soap and detergents.
  • Fuel combustion and energy production.
  • Environmental protection and pollution control.

The periodic table organizes all known elements based on their atomic number, electron configuration, and chemical properties. It helps predict element behavior and trends.

Physical Change: No new substance is formed (e.g., Melting ice, Boiling water).
Chemical Change: New substances with different properties are formed (e.g., Rusting, Burning).

Matter exists in different states:
  • Solid: Fixed shape and volume (e.g., Ice).
  • Liquid: Fixed volume but takes the shape of the container (e.g., Water).
  • Gas: No fixed shape or volume (e.g., Oxygen).
  • Plasma: High-energy ionized state (e.g., Sun, Lightning).

A degree in Chemistry can lead to careers in:
  • Pharmaceuticals & Medicine
  • Chemical Engineering
  • Environmental Science
  • Food & Beverage Industry
  • Research & Development
