Air hole open=steadyAir hole closed= not steady.Why?Lack of oxygen makes the flame unsteady when the hole is closed as oxygen is used for burning.

Yes, when the air hole of a Bunsen burner is closed, it can produce a roaring or buzzing sound due to incomplete combustion of the gas. This can result in a build-up of unburned gas that ignites intermittently, creating noise.

∙ 11y agoThis is the roaring flame. It is characterised by a light blue triangle in the middle and it is the only flame of the 3 which makes a noise. It is approximately 700°C.

When air hole of the Bunsen burner is closed what is the observation?
When the air hole of a Bunsen burner is closed, the flame will be yellow and sooty. This occurs because without sufficient air supply, incomplete combustion of the gas produces a sooty flame.
Word equation for the air hole on a Bunsen burner is closed?
When the air hole on a Bunsen burner is closed, it restricts the flow of air into the burner. This can result in incomplete combustion of the gas, leading to a yellow, sooty flame instead of a blue, clean flame. Adjusting the air hole allows for the correct air-to-fuel ratio, producing an efficient and clean flame for heating or sterilizing purposes.
What was the feature that allowed the Bunsen burner to get a hot flame?
The feature that allowed the Bunsen burner to generate a hot flame is the adjustable air vent at the bottom of the burner. By controlling the amount of air entering the burner, the user can regulate the combustion process to produce a hot and clean flame for various scientific experiments and heating applications.
What is the movable part of a Bunsen burner?
The movable part of a Bunsen burner is called the air hole or air vent. By adjusting the air hole, you can control the amount of oxygen mixing with the gas, which in turn affects the type of flame produced by the burner.
How do you turn off the Bunsen burner?
To turn off a Bunsen burner, first close the air hole at the base of the burner by turning the metal collar clockwise until it's fully closed. Then turn the gas knob on the burner clockwise until it stops to shut off the gas supply. Let the burner cool down before handling it.
Is the hole open or closed on a Bunsen burner to make a safety flame?
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
What temperature is a Bunsen burner when the air hole is closed?
When the air hole of a Bunsen burner is closed, the flame temperature can reach up to around 1,400°C (2,550°F). This is because the closed air hole restricts air from entering the burner, leading to incomplete combustion and a hotter, more sooty flame.
Can the the flame of closed air hole Bunsen burner can used for heating?
Yes, the flame of a Bunsen burner with a closed air hole can still be used for heating, but it will produce a cooler, more yellow flame compared to a Bunsen burner with an open air hole. Adjusting the air hole allows for control of the flame temperature.
Does a Bunsen burner make a noise when the air hole is open?
Yes, a Bunsen burner will make a noise when the air hole is open due to the increased flow of oxygen combining with the gas to create a louder, more pronounced flame.
What is the name when the air hole is closed on a Bunsen burner?
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
How much amount of heat is there if the air hole of the Bunsen burner is closed?
If the air hole of a Bunsen burner is closed, the flame will burn yellow with a lower temperature and produce less heat compared to when the air hole is open. The amount of heat produced would be reduced as the combustion is incomplete due to the lack of sufficient oxygen.
Why do you need to ensure that the air hole is closed before you light the bunsen burner?
it's to prevent a strike-back
What happens when the hole on a Bunsen burner is closed?
When the hole on a Bunsen burner is closed, the air supply is cut off, which disrupts the combustion process. As a result, the flame will either extinguish or decrease in size and intensity. By controlling the airflow through the hole, you can adjust the flame's temperature and characteristics.
When you are not using a Bunsen burner but wish to leave the flame on you should always leave the air hole closed why?
It is less hot
What is the colour of the Bunsen burner when it is halfway closed?
When the hole of a Bunsen burner is half closed (or half open) the flame is mostly blue-violet in color throughout, with no orange/yellow apparent as it would be with the hole fully closed. When the hole is fully open, the flame divides into a pale voilet color outer part with a cone of intense blue color within.
What covers air hole in a burner?
The function that covers the air hole in a Bunsen burner is the collar.
When air hole of the Bunsen burner is closed what is the observation?
When the air hole of a Bunsen burner is closed, the flame will be yellow and sooty. This occurs because without sufficient air supply, incomplete combustion of the gas produces a sooty flame.
