NCERT Solutions for Class 9 Science: Chapters Details and Concepts

NCERT Solutions for Class 9 Science Chapter 1 Matter in Our Surroundings

Class 9 Science Chapter 1, Matter in Our Surroundings, introduces students to the concept of matter and its physical properties. Everything around us that occupies space and has mass is called matter. Earlier, Indian philosophers described matter using the Panch Tatva: air, water, earth, sky, and fire. Modern science classifies matter based on its physical properties and chemical nature.


In this chapter, students learn that matter is made up of tiny particles. These particles have spaces between them, are in continuous motion, and attract each other. Based on these characteristics, matter exists in three states: solid, liquid, and gas. Each state is explained in detail using activities to help students understand their differences.


The chapter also explains that the state of matter can be changed by altering temperature or pressure. Important processes such as melting, freezing, condensation, sublimation, and evaporation are discussed. Special focus is given to evaporation, its factors like surface area, temperature, humidity, and wind speed, and how evaporation causes cooling.


Topics Covered in Class 9 Science Chapter 1 Matter in Our Surroundings

  • Definition of matter

  • States of matter: solid, liquid, and gas
