How many distinct cones a properly adjusted nonlaminous flame on Bunsen b?
A properly adjusted nonluminous flame on a Bunsen burner has two distinct cones: the inner blue cone, which is the hottest part where complete combustion occurs, and the outer yellow cone, which is where incomplete combustion occurs.
What happens when you heat liquids?
It depends on what liquid you heat, and if is an open flame or just an element, like gas+open flame is very dangerous while water+open flame causes a reaction of steam to rise. im not the greatest at science but i know somethings, but somethings boil, some just evaporate and some do even more things but im not a science person siz
What happens to the flame when you open and close the air hole?
When you open the air hole, more oxygen is supplied to the flame, causing it to burn brighter and hotter. Closing the air hole restricts the oxygen supply, leading to a smaller and weaker flame, or it may extinguish the flame if there is not enough oxygen to sustain it.
What happens when you put balloon on top of a fire?
If a balloon is placed on top of a fire, the heat will cause the air inside the balloon to expand rapidly, potentially causing the balloon to burst or pop. The rubber material of the balloon is not flame-resistant and could catch fire. It is not safe to place a balloon on top of a fire.
Why a candle gets extinguish when a glass is put over it?
When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.
Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
What happens to denim when it is placed in a flame?
burns
Describe and explain what happens to the piece of wooden splint when it is placed in the different parts of the Bunsen flame?
When a wooden splint is placed in the outer part of the Bunsen flame, it burns with a smoky flame due to incomplete combustion. When placed in the inner blue cone of the flame, it burns with a clean, non-smoky flame due to complete combustion of the wood. The inner blue cone is the hottest part of the flame, which allows for more efficient burning.
How do you get blue flame to yellow flame?
To change a blue flame to a yellow flame, you can adjust the air mixture going into the gas burner. Increasing the amount of air mixed with the gas will result in a yellow flame. This can usually be done by adjusting the air shutter on the burner.
Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light. The sun is luminous; the moon is non-luminous.
Is the temperature of a luminous flame greater ot less than that of a nonluminous flame?
The yellow color in a luminous flame is basically the black-body emission from hot particles of soot in the flame. they are hot, and they glow like the filament of a light bulb. In a blue flame, there are no particles of soot to give that incandescent radiation. Instead, the main color you see is blue emission from the high-energy C2 molecule.
What is a sentence using the word flame?
The flame of the candle was placed too close to the centerpiece.
what is deposited when an evaporating dish is put on top of a luminous flame?
luminous flame gives partial combustion so you can see some black unburnt vapours deposited on the plate
How many distinct cones a properly adjusted nonlaminous flame on Bunsen b?
A properly adjusted nonluminous flame on a Bunsen burner has two distinct cones: the inner blue cone, which is the hottest part where complete combustion occurs, and the outer yellow cone, which is where incomplete combustion occurs.
What happens to a evaporatind dish when placed over a luminous flame?
it doesnt change its color
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.
Why must the size of the test flame be kept very small?
Keeping the test flame size small ensures consistent and controlled conditions for conducting the test. A small flame also helps in observing the characteristics of the substance being tested more accurately and allows for better comparison with known standards. Additionally, a small test flame minimizes safety risks and potential variability in results.
