Occupational therapy is about helping people do the day-to-day tasks that occupy their time, sustain themselves, and enable them to contribute to the wider community. It is these opportunities to do, which occupational therapy provides, that prove important and meaningful to the health of people.
A burning candle produces a luminous flame. What is the fuel for a burning candle? Why is the flame luminous? The fuel for candles is the wax as well as the oxygen. The candle experiences this type of flame because there is an insufficient amount of oxygen being burned.
In a premixed flame, the oxygen and fuel are premixed beforehand, which results in a different type of flame. Candle flames (a diffusion flame) operate through evaporation of the fuel which rises in a laminar flow of hot gas which then mixes with surrounding oxygen and combusts.
