State whether the following statements are true or false. In case a statement is false, write the corrected statement in your notebook.

Condensation of steam is not a chemical change.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation of the correct option

Chemical change :

• A substance is said to undergo a chemical change when the chemical properties of a substance alter. As a result, there is either formation or breaking of atomic bonds at the molecular level.

Physical change :

• A substance is said to undergo a physical change when only the physical properties such as the shape, size, color, state, or appearance of the substance change. Its chemical composition remains intact.

Condensation of steam:

• During the condensation of steam, the physical state of the water is changed from gaseous to liquid.
• Therefore it is a physical reaction.

Hence the given statement is true.
