Why does turning the collar on a busen burner make the flame hotter?
Flames need air to expand and grow, or become hotter. The oxygen circles the flame and makes the flame alter. The collar allows air to get to the flame.

How do you correct a yellow flame on a Bunsen burner?
The flame of a Bunsen burner can potentially reach up to 1100-1200 degrees Celsius. On the bottom of the burner there is a ring which open and closes the way of oxygen from air to the gas. When the ring is open the oxygen flows to the gas and the flame becomes blue ( this is hotter flame :) if you close the ring the burning will be without oxygen and the flame will by yellow-red ( this one is cooler ). So the temp. of the Bunsen burner depends on the ring. If i remember correcty the tip of the blue flame is the hottest ( i think but not sure 1600 degrees Celsius).
Do closing air-holes on a Bunsen burner make the flame hotter?
Because more air is able to fuel the flame's reaction; the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter.
How do you get a blue flame with the Bunsen burner?
The blue flame is obtained when the collar is rotated to open the hole fully. This adds lots of oxygen to the burn mix and ensures complete oxidisation (ie blue flame).
How does luminous flame exist?
because of the yellow flame, yellow is a bright coulor........... Scientific term......... The collar is closed to get luminous flame and collar open to get non- luminous flame....

The flame itself will get bigger/hotter, and the amount of 'blue' increases. Depending on the type of burner, it may or may not increase proportionately with the total flame size.
