Describe the changes that take place when a match burns Are these changes physical or chemical changes?
When a match burns, the heat causes the matchstick to undergo a chemical reaction with oxygen in the air, releasing energy in the form of heat and light. This is a chemical change because the composition of the matchstick changes as it reacts with oxygen to produce new substances like carbon dioxide, water vapor, and ash.
Are all physical changes are reversible changes?
Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.
