Uses of carbon
1. Dry ice – Dry ice is solid carbon dioxide. It is frozen carbon
dioxide with a temperature of -78.5°C and melts into a gaseous rather
than liquid form to create the popular smoke effect.
2. Fizzy drinks – When held under pressure carbon dioxide dissolves
in water, and it then causes bubbles on your tongue as it forms a
carbonic acid as you take a gulp.
3. Carbon dating – The age of fossils and minerals can be found by
using carbon-14 which is a radioactive isotope of carbon. This is
covered in depth in issue 7 of How It Works.
4. Teeth whitening – Carbon is a key element involved in teeth
whitening treatments, found as carbon amide peroxide in both dentist
and over-thecounter treatments.
5. Fire extinguishers – A fire extinguisher containing carbon
dioxide is mainly used for fighting electrical fires. The carbon goes
back into the atmosphere without leaving any harmful fumes.
