Why do you have to use wire gauze in heating beaker?
the base of an evaporating dish is rounded and will not be stable when placed on a gauze, hence a triangle (tripod) to hold its base better . Also, when you heat the beaker, you put the wire gauze above the triangle(tripod) and the triangle(tripod) above the Bunsen burner.
What is the purpose of a wire gauze to a Bunsen burner?
It is to prevent direct contact of the glass with the flame of the Bunsen burner. This lowers the possibility of the glass shattering when being heated Read more: What_is_the_purpose_of_the_wire_gauze_placed_over_a_bunsen_burner
What is used to secure a beaker or flask to the ring stand?
wire gauze placed on top of the iron ring.
Laboratory tools for supporting containers being heated?
iron stand, iron ring, wire gauze, tripod
What happens when a wire gauze mat is placed over the flame on a Bunsen burner?
This serves to spread out the point of application of the heat.
Function of a gauze many?
The primary purpose of a wire gauze mat is to support a container (such as a beaker or an Erlenmeyer flask) while it is being heated. The gauze mat also helps with an even distribution of heat as the Bunsen burner flame passes through the gauze to the container.
Why a gauze is often placed over a burning flame for heating an object?
To prevent flame impingement on the vessel being heated, which could damage the vessel. A flame cannot pass through a gauze (or screen). as a proof you could set up a bunsen burner beneath a wire gauze. Turn the gas on and ignite the gas above the gauze. you will notice the flame will stay above the gauze. If you ignite the flame beneath the gauze and lower the gauze into the flame, the flame will not pass above the gauze. Yet, if you light both below and above the gauze you will have flame on both sides. Indicating that flames impinging on the gauze do not burn the gas completely and the gas will pass through the gauze.
When Bunsen burner is lit below a wire gauze the flame initially burns below the gauze after sometime the flame burns both below and above the gauze explain this observation?
At first, the air above the gauze is cold and heavy therefore, it cannot be ignite. After sometime, the hair above gets heated and becomes light hence can be ignited thus the flame burns above the gauze. Guys rate my answer please 😉💫
Why does the wire gauze not burn under heat?
Actually wire gauze will burn when heated. I think you may instead be asking "Why will a flame not propagate beyond a wire mesh." But the answer to your question is: "A wire gauze WILL burn under appropriate heat."

Why does a flame not get extinguished when a wire gauze was placed on top of it in a candle observation chemistry lab?
A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.
What Stand used when heating beaker or flask?
You havesome options to get this done. The first is to set up a tripod with some wire gause across the top and place a Bunsen burner underneath, place the beaker on top and it will heat it. A much better way to do this is to use a hotplate and a magnetic stirrer, these hotplates are designed to got to specific temperatures. For round bottomed flasks an oil bath is put on top of the hotplate and the flask clamped into the oil and a magnetic stirrer placed in the oil bath, the round bottomed flask is clamped in place with a retort stand and clamp.
How is a wire gauze square used?
Generally it is used with a ring stand and a ring. The wire gauze is placed on the rind, a beaker or flask is placed on the gauze, and heat is applied by a Bunsen burner.

What is gauze for?
Gauze is used for bandaging wounds, cuts, etc.
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 is it that an ice that is wrap in wire gauze does not melt when heated in a beaker of water?
Since the wire gauze is a good conductor of heat, all the heat is sttracted to the wire gauze
