What is Changes Around Us Class 7?
This chapter explains that changes around us can be grouped into physical changes and chemical changes. In a physical change, only the form, size, shape, or state of a substance changes, and no new substance is formed. In a chemical change, a new substance is formed and the change is usually permanent. Students also learn about reversible and irreversible changes through familiar examples from daily life. Standard revision notes for this topic focus on these classifications and their examples, such as melting, rusting, burning, and curd formation.
