Physical And Chemical Changes Class 7 Lesson Plan In Hindi
- Changes of state: These changes involve a substance changing from one physical state to another. For example, ice melting into water or water vaporizing into steam.
- Dissolving: This change involves a solid dissolving in a liquid to form a homogeneous mixture. For example, sugar dissolving in water to make a sugar solution.

- Combustion: A type of chemical reaction where a substance reacts with oxygen to produce heat and light. For example, burning wood or coal.
- Oxidation: A chemical reaction that involves the loss of electrons from a substance. For example, rusting of iron or tarnishing of silver.
- Decomposition: A chemical reaction where a compound breaks down into simpler substances. For example, when hydrogen peroxide breaks down into water and oxygen.
- Synthesis: A chemical reaction where two or more substances combine to form a new compound. For example, when hydrogen and oxygen combine to form water.
- Acid-base reactions: A type of chemical reaction where an acid reacts with a base to form a salt and water. For example, when hydrochloric acid reacts with sodium hydroxide to form sodium chloride and water.
- Precipitation: A chemical reaction where two soluble compounds react to form an insoluble compound (precipitate). For example, when silver nitrate reacts with sodium chloride to form silver chloride, which is insoluble and forms a white precipitate.

- Reversibility: Physical changes are usually reversible, meaning that the original substance can be recovered by reversing the change. Chemical changes, however, are often irreversible, as the original substance is transformed into a new substance.
- Energy changes: Physical changes generally do not involve any energy changes, whereas chemical changes often involve an energy change, such as the release or absorption of heat, light, or electricity.
- Examples: Examples of physical changes include melting of ice, boiling of water, or bending a wire. Examples of chemical changes include burning wood, rusting of iron, or digesting food.
- Observability: Physical changes are often easier to observe, as they usually involve a change in the physical properties of a substance that can be seen, felt, or measured. Chemical changes are often less observable, as they often involve changes at the molecular or atomic level that are not visible to the naked eye.
Lesson Plan for Class 7 on Physical And Chemical Changes In Hindi
In conclusion, physical and chemical changes are two different types of changes that occur in matter.
Physical changes involve a change in the physical properties of a substance, such as its shape, size, or state, without changing its chemical composition.
On the other hand, chemical changes involve a change in the chemical composition of a substance, resulting in the formation of a new substance.
