When camphor is heated, which of the following changes will take place?

The correct answer is Solid to gas. Key Points

• When camphor is heated, it sublimates directly from a solid to a gas state without passing through the liquid state.
• This is because camphor has a low melting point and a high vapor pressure, which means that it can easily transition from a solid to a gas without melting into a liquid first.
• Camphor is a white crystalline substance that is commonly used in medicine, as well as in the production of plastics, fragrances, and insecticides.

Additional Information

• The wood and bark of the camphor tree were the primary sources of the powder known as camphor.
• Nowadays, synthetic camphor predominates.
• It is present in some skin care products, including as treatments that have FDA approval.
• It's a typical component of topical treatments for skin irritation and cough.
