Question

Can matter undergo chemical changes on heating?

Answer 1

Yes matter undergo chemical changes on heating.

Substances change all around us. They change depending upon their chemical make-up and what is done to them.

For example, a physical change does not result in the formation of new substances. Physical changes alter only the size, shape, form or matter state of a material. Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes.

On the other hand, chemical changes are a bit different. In a chemical change, a new substance is formed. The chemical change also usually involves heat, burning, or other interaction with energy. There are five rules of thumb that usually determine if a chemical change occurs:

• Color change
• Gas is given off
• A new substance forms
• Heat is given off (exothermic)
• Heat is required (endothermic)
