A Bunsen burner focuses a lot of heat straight upward, instead of outward. This allows you to heat something up at close range without your hand or anything else getting too hot. Most Bunsen burners have a valve that controls gas flow and adjustable vents where you can control the amount of air that feeds the flame. Bunsen burners are a safe, practical way to apply heat in a chemistry lab.
i am not sure can someone else answer this please
the iron ring, the wire mesh over the ring, the beaker or whatever else was being heated. There are special tongs for most types of glassware or porcelain objects that are heated over a Bunsen burner.
The same sort of burns you would get from anything else, depending on the heat of the flame and the duration of exposure. A Bunsen burner is not anything special. It is just designed to burn methane cleanly and efficiently in the presence of oxygen gas to form carbon dioxide and water vapor as the only by-products.

They are used in practical experiments, particularly chemistry, to hold test tubes, burettes etc in position over something else such as a Bunsen burner or beaker.

A tripod is a device that has three legs and is used to hold something. It is often used in photography.
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
Experience, or indeed a little foresight shows that holding it anywhere else will result in getting your fingers or tongs burnt in the flame. Usually the thing you are trying to heat is at the bottom of the tube and the neck is farthest away from that.
