Physical and Chemical Changes
Physical changes are reversible changes that do not involve a change in the chemical composition of a substance. Examples of physical changes include changes in state (solid, liquid, gas), changes in shape or size, and changes in color or texture. In contrast, chemical changes involve a change in the chemical composition of a substance, resulting in the formation of a new substance(s) with different properties.
Explanation
Of the given options, option 'D' - combustion of liquefied petroleum gas (LPG) is not a physical change. Combustion is a chemical change that involves the reaction of a fuel (LPG in this case) with oxygen in the air, producing heat and light energy. The products of the combustion of LPG are carbon dioxide and water vapor, which are different from the original fuel.
On the other hand, boiling of water to give water vapor, melting of ice to give water, and dissolution of salt in water are all physical changes. In these processes, no new substances are formed, and the original substance(s) retain their chemical composition.
Conclusion
In summary, physical changes are characterized by the absence of a chemical reaction, and the original substance(s) retain their chemical composition. Option 'D' is the correct answer as it represents combustion, which is a chemical change that involves the formation of new substances with different properties.
