To answer this question, you need to understand how heat conduction and combustion work. Here is a possible answer:
When Bunsen gauze gets hot, you see different effects depending on where you light the gas. If you light the gas below the gauze, the flame will only appear at the bottom, but not above the gauze. This is because the gauze is a good conductor of heat, and it takes away the thermal energy that would otherwise ignite the gas above the gauze. If you light the gas above the gauze, the opposite happens. The flame will only appear at the top, but not below the gauze. This is because the gauze also prevents the hot gas from mixing with the cold gas below, which is necessary for combustion.
In some cases, you might be able to lift the flame up with the gauze, if you do it very slowly. This is because the gauze becomes hot enough to ignite the gas above it, and the flame follows the heat source. However, this is not a reliable or safe method, and it should only be done as a demonstration by a teacher.

How could you use a piece of iron wire to find the hottest part of a Bunsen burner?
by having 4 iron wires and placing each one of them in different parts of the flame observe the wire then record results not what wire is placed at what part of the bunsen then see which one is the most red (the more red the more hot the area of the flame you have out it on for it to be a fair test you should have the bunsen on a yellow/orange flame and hover the wire with tongs at the different areas do not change to a blue flame for a different wire,this was out of common sense but i dont know if my theory is correct
Why are you more likely to see a mirage on a hot day than on a mild day?
The density of air increases as the air gets cooler. The greater the difference in densities is, the more the light refracted.
Why must you close the air hole of the Bunsen burner when you are not heating anything?
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.
What are some disadvantages of hot air balloons?
Hot air balloons are a slower form of transportation. For most people, they are beautiful to see when they are in the air.
When checking to see if a door is hot the first thing that you do is?
Hold your hand NEAR it and see if you can feel any radiated heat. Do not touch it!
Wire gauze functions?
Wire gauze can be used to support a container (such as a beaker or flask) during heating. When the Bunsen burner flame is beneath it, with a tripod, the wire gauze helps to spread the flame (and heat) out evenly over the container. It is frequently used in combination with an iron ring and ring stand with a Bunsen burner underneath it (see the Related Questions for more information about an iron ring, ring stand, and Bunsen burner & tripod). A clay triangle serves a similar purpose, except that a clay triangle is used for a crucible instead.

Why should you use the yellow flame when the Bunsen burner is unattended?
Safety. The yellow flame is easier to see and burns much less hot.
Why do people see meteorites when they get close to Earth?
It gets more hot and burns . then you see the light as it gets closer to the sun.
When did Michael Faraday invent the Bunsen Burner?
Bunsen didn't invent the Bunsen Burner. Peter Desaga did on the request from Bunsen. It was around 1855. See the referenced wiki page below for the full story
The history of the Bunsen burner?

Base in Bunsen burner?

Why is it better to use a blue flame on a Bunsen burner?
It's hot, for one. The Bunsen burner's blue flame is unusual, however, in that it emits little light, so it can be difficult to see under some circumstances.
Where did the word Bunsen come from?
If you are referring to a Bunsen burner, used in laboratories to heat chemicals, it was named for it's inventor- Robert Bunsen. See link at bottom of page.
How is the Bunsen burner maintained and installed?

Describe the procedure of making copper sulphate crystal using copper oxide and sulfuric acid?
Equiptment: Bunsen Burner, tripod, Gauze, heatproof mat, basin, stirring rod, spatula, measuring cylinder, Funnel, filter paper, Chemical; CuO+H2SO4First measure 20cm3 of sulphuric acid, H2SO4, using a measuring cylinder and pour it into the beaker.Take 1 spatula of copper (II) oxide and put it into the same beaker.stir the mixture using a stirring rod to ensure complete neutralisation of the acidAdd excess CuO if required.Filter the mixture into a basin.Turn on Bunsen burner but make sure it is on the heatproof mat, and then put the tripod on top of the Bunsen burner followed by the Gauze and basin containing CuSO4.Heat the filtrate until you begin to see crystals forming around the basin.Turn off Bunsen burner and leave to dry.
Is a Bunsen burners flame easy to see it is open?
yes
