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.
It's to allow air to mix with the gas before burning - creating a hotter flame.
Because, with the air-hole open, the burner creates a pale blue, much hotter flame - which is difficult to see. Closing the hole creates a yellow flame which is easier to see.
When it is on a blue flame because the blue flame is hotter than the yellow flame due to the mixture of air and gas. Im Year 7 Guys you should know this!
As more air enters the Bunsen Burner, the flame turns from a flickering (wax candle effect) yellow to a fierce sounding blue, much hotter, flame.
The collar regulates the amount of air which mixes with the fuel gas before it is burned. If the hole in the collar is not lined up with the hole in the bunsen stem, the fuel does most of its mixing with air at the top of the burner. This makes burning inefficient and the flame is cool. When the two holes line up, air is pre-mixed with the fuel, burning is much more efficient and the flame is as hot as possible.the collar of a bunsen burner is the part which doesnt get hot and you can twist it to close or open the air hole.Turning the collar opens and closes the air-hole which allows a controlled amount of oxygen to mix with the gas. The amount of air mixed in determines the colour and heat of the flame.The collar controls the amount of air and thus oxygen that can reach the methane gas inside the burner. With the hole closed there is no additional oxygen to mix with the methane and so we have a yellow flame. Opening the hole allows oxygen to mix with the methane so it burns at a higher temperature and with a blue flame.The collar on the Bunsen burner is to allocate as much oxygen as desired from the atmosphere into the Bunsen burner. The more oxygen in the Bunsen burner, the bluer or clearer the flame is. It is much hotter when in the blue flame.
By using the correct ratio of oxygen and fuel mixture. Opening the air hole in the Bunsen burner increase the oxygen which helps the flame burner hotter .
Because your letting in Oxygen.
Turn the collar and the flame will get hotter
its hotter than a yellow flame
The tip of the inner flame is the hottest.
Opening the air hole collar to mix air with the fuel gas results in a hotter flame.
because it's hotter.
cuz ur tubby
It's hotter than the yellow flame.
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.
The bottom of a Bunsen burner contains holes that allow air flow. When there is no air flow, the temperature of the flame will be hotter. With the holes wide open, the flame will not be as hot.
