Chapter 1: Chemistry As A Science Of Matter | Learnify

Описание: Chemistry explains what matter is made of and how it transforms.
This chapter builds the foundation for thinking like a chemist.
Chapter 1: Chemistry as a Science of Matter introduces chemistry as a central science that connects physics, biology, and materials. Instead of memorizing reactions, this chapter focuses on how chemists observe, model, and explain changes in matter.
In this video, you will understand what makes chemistry different from physics and biology, and why chemistry focuses on composition, structure, and transformation of matter. The role of models and theories is explained clearly, showing how experimental evidence supports or refines chemical ideas.
The chapter introduces the three levels of chemical understanding — macroscopic, microscopic, and symbolic — helping you connect laboratory observations with particle-level explanations and chemical equations.
You’ll learn the laws of chemical combination, understanding how mass and composition are conserved and related during chemical reactions. These laws form the logical basis of stoichiometry and chemical calculations.
Measurement and uncertainty are discussed to show how experimental data is recorded, how significant figures reflect precision, and why accuracy matters in chemistry.
Finally, dimensional analysis is introduced as a powerful tool for checking calculations and converting units correctly, helping you avoid common numerical mistakes.
This lesson is ideal for high school and undergraduate students, medical and engineering aspirants, and anyone preparing for board exams, JEE, NEET, Olympiads, or university-level chemistry. A strong foundation here makes atomic structure, stoichiometry, and physical chemistry much easier.
