If you add too much air to a fire in a Bunsen burner the fire cools or is blown out but what happens during the time the fire cools?

The fire doesn't actually "cool". Fire needs 4 things to occur, known as the fire tetrahedron. It needs fuel, oxygen, heat, and a sustained chemical reaction between the three. If too much "air" is added, you are basically robbing the fire of it's fuel source because the ratios are off due to the air/fuel ratio. It becomes to lean to burn any longer. As the flame on the burner becomes robbed of the oxygen it needs and becomes leaner, it begins to produce less btu's, the measure of heat.

What use of bernoulli's theory?
Bernoulli's therem used to tell about lift of an air craft wing, Blowing of roofs, Bunsen burner.In bunsen burner, the gas comes out of the nozzle with high velocity.Due to this the pressure in the stem of burner decreases. So air from the atmosphere rushers into the burner. During a storm, the roofs of huts or tinned roofs are blown off without any damagd to other parts of the hut. The blowing wind creates a low pressure on the top of the roof. The pressure under the roof is however greater than on the roof. Due to this pressure difference, the roof is lifted and blown off with the wind./
