Understanding the Context

Chapter-10 Earth — Our Shared Home The Blue Planet “After seeing the Earth from outside the first thought that came to mind was that, the Earth looks completely one, no border is visible from outside.

Key Insights

Matter can be studied in solid, liquid, gas and plasma states, in isolation or in combination. Chemistry, often called the “central science,” is the branch of science that deals with the composition, structure, properties, and changes of matter. It connects the other natural sciences, including physics, biology, and geology, by explaining how substances interact and transform. Chemistry is the science of the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. Everything is made of atoms.
