In the first section of the chapter, the physical nature of matter is discussed. Under this, the focus is given on the particles which form these matters and secondly, the size of these particles. The second section of the chapter, Matter in Our Surroundings discusses the characteristics of particles of matter. Here, the following three characteristics are discussed: Particles of matter have space between them Particles of matter are continuously moving Particles of matter attract each other The above properties are explained with the help of activities. The third section of the chapter, Matter in Our Surroundings lays emphasis on the three states of matter: The solid state The liquid state The gaseous state In the fourth section, the effect of change of temperature and pressure on the matter is discussed with the help of examples, demonstrations and activities. In the last section of the chapter, the concept of evaporation is covered along with the factors affecting the process of evaporation. The other two states of matter: plasma and Bose-Einstein condensate are also discussed at the end of the chapter, Matter in Our Surroundings along with the other three states. The chapter, Matter in Our Surroundings is covered under the following sections -  1.1 Physical Nature of Matter 1.2 Characteristics of Particles of Matter 1.3 States of Matter 1.4 Can Matter Change its State? 1.5 Evaporation Chapter 1 of CBSE Class 9 Science is entitled "Materials in Our Environment ''. In this chapter, students learn about the physical properties of matter, the properties of matter particles, states of matter, and evaporation. This is an important chapter in the CBSE Grade 9 science curriculum that provides a foundation for understanding matter and its nature. Students can better understand the main concepts of the chapter by practicing answering questions with NCERT notes for 9th Grade Chapter 1 Science about substances, interconversion of substances, evaporation, etc. Vidyakul provides over 450 exercises covering all the subtopics covered in Chapter 1.
