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.
The wick draws the liquid wax up toward the flame. As the liquid wax gets close to the flame, it gets hot enough to turn into wax vapor, a gas. The wax vapor is really what is burning to make the flame. As the candle flame burns, it always tends to stand straight up. This is because of the movement of the air around it. The flame heats the molecules in the air, making them move faster and spreading them out. This air is less dense and is pushed up by the cooler air below the flame.
