ROTATING VANE APPARATUS
In this video you will be learning how to demonstrate the effect of convection currents in air.
This model can be used in science exhibitions / science fairs etc.
And also teachers can use this model to demonstrate the effect of convection currents in air in their class room / Science lab.
Q.Why the vane or fan is rotating?
Physics Behind:
When the candles are lit, the air in the vicinity of the candles heated and being lighter the air rises and causes the cold air to move out and sink. This movement causes the vane to rotate. Thus it indicates the flow of convection currents in an upward direction.
