Why does The smoke from a bonfire rises upwards?
The smoke from a bonfire rises upwards due to the difference in temperature between the smoke and the surrounding air. As the hot smoke rises, it mixes with the cooler surrounding air, creating vertical movement. Additionally, the heat from the fire creates a convection current that helps propel the smoke upwards.
Why does smoke rise quickly?
Smoke rises quickly because it is less dense than the surrounding air. As the smoke is heated, it becomes lighter and more buoyant, causing it to move upward due to the difference in densities between the smoke and the surrounding air. This creates a thermal draft that propels the smoke upwards.
