Understanding Sublimation of Camphor
Sublimation is a fascinating process where a solid turns directly into a gas without passing through the liquid phase. The sublimation of camphor is a classic example of this physical change.
Characteristics of Physical Change
- No New Substance Formed: During sublimation, camphor changes from solid to gas, but its chemical composition remains the same. This means that the identity of the substance does not change.
- Reversible Process: The process can be reversed. When the gas cools down, it can condense back into a solid form of camphor. This reversibility is a key feature of physical changes.
- Energy Changes: Sublimation involves energy changes in the form of heat. Solid camphor absorbs energy from the environment, allowing it to transition to a gaseous state.
Why Not Chemical Change?
- No Chemical Reactions: A chemical change involves the breaking and forming of chemical bonds, resulting in new substances. Since camphor retains its properties and does not form new substances during sublimation, it is not considered a chemical change.
Conclusion
Therefore, the sublimation of camphor is classified as a physical change due to its reversible nature, the absence of new substances, and the preservation of the original chemical identity. Understanding these properties helps in distinguishing between physical and chemical changes in various substances.

Sublimation is classified as a physical change because it involves a solid transitioning directly into a gas without passing through the liquid state. This process is reversible, allowing camphor to return to its solid form when cooled.
