NCERT Solutions for Class 9 Science Book Chapter Summary

Chapter 1: The Matter in Our Environment

The textbooks for Class 9 science begin with the chapter “Matter in Our Surrounding.” Everything we see is made out of stuff, referred to as matter. These objects have mass and take up space.

Particles make up matter, and these particulars are minuscule. Matter particles have space between them, are constantly moving, and attract. Solids, liquids, and gases are the three states of matter surrounding us. Variations in the characteristics of the matter particles give rise to these states of matter. With the help of activities, all three states of matter have been thoroughly explained. Changing the temperature or pressure can alter the state of matter. Evaporation transforms a liquid into a vapor at any temperature below its boiling point. The evaporation rate is affected by the surface area exposed to the atmosphere, temperature, humidity, and wind speed.
