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.
Is making oatmeal a chemical or physical change?
Making oatmeal involves both physical and chemical changes. The physical change occurs when oats absorb water and swell, altering their texture. A chemical change can also happen as the heat causes starches in the oats to gelatinize, changing their chemical structure and flavor. Overall, the process predominantly features physical changes, but the cooking aspect introduces some chemical changes as well.
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.
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.

What are some of the non physical changes which occur during adolescence?
There are many non-physical changes that occur during adolescence, most notably the large increase in the number of conections between neurons in the brain. this is what causes the sporadic behaviour in adolescents, and helps the brain and personality to develop by 'trimming' the unnecessary synapses. The flood of hormones (testosterone and oestrogen in men and women respectively) that causes the physical changes also cause a development in the sexuality of the adolescent (it makes the horny).
