Why is it no use to heat something close the chimney of a Bunsen burner?
It will not burn.
Why do you have to use the yellow flame when not using the Bunsen burner?
You don't have to use the yellow flame but its not recommended for heating as its a lot cooler than the blue 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).
What is the hottest part of the roaring Bunsen burner flame?
The blue part of the flame, the cone in the middle is the hottest, the flame cools as it gets further away from the burning centre, this is similar to the sun where the outer surface of the sun is significantly cooler compared to the inside.

What is the purpose of the airhole in the Bunsen burner experiment?
T%o increase the temperature of the flame. When seen as a yellow slack flame, it is quite cool. This is when the air-hole is closed. When seen as a pale blue roaring flame, it is much hotter. This is when the air -hole is open.

Why does the airhole have to be closed when lighting a Bunsen burner?
Because if the air hole was wide open, the flame will be blue, which is going to be really hot so you have to leave it at a safety yellow flame which is when the air hole is closed when lit. It could be dangerous to leave a Bunsen burner on a blue flame. this is confusing, explain more clearly, geez is dat too much to ask?
What happens when I hold a wet cardboard over a Bunsen burner flame vertically and horizontally?
Because the position of the cardboard is vertical it obviously displays the intensities of theheat. The bottom of the cardboard displays the hottest part of the flame where the char is firstseen. While the top area of the cardboard took time to dry up and char because is cooler in thisarea that those at the bottom.
Why does water cause cooling?
Because the water is cooler the hot touch that you have causes the water to be cooler than what is is actually.

What causes a 1998 Ford Taurus transmission to overheat?
