Physical And Chemical Changes Class 7 Worksheets With Answers

Physical and Chemical Changes Class 7 Worksheets with Answers

In class 7, students are introduced to the concepts of physical and chemical changes. These changes occur when substances undergo a transformation in their properties. To help students practice and reinforce their understanding of these concepts, worksheets are often used as a valuable learning tool. Here, we will provide you with an overview of physical and chemical changes class 7 worksheets with answers.

Physical Changes

A physical change refers to a change in the physical properties of a substance without altering its chemical composition. In other words, the substance remains the same at the molecular level. Examples of physical changes include melting, freezing, boiling, condensation, evaporation, and changes in shape or size. Physical changes are usually reversible.

Chemical Changes

A chemical change, on the other hand, involves the transformation of one or more substances into new substances with different chemical properties. This change occurs at the molecular level, resulting in a new composition. Chemical changes are typically irreversible. Examples of chemical changes include burning, rusting, digestion, fermentation, and the formation of new compounds.
