When a flame comes into contact with glass, the glass rapidly absorbs heat from the flame, leading to a sharp temperature drop at the point of contact. This sudden cooling can extinguish the flame by interrupting the combustion process, as the fire requires a certain temperature to sustain itself.

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.
Can water go through glass?
Yes, water can pass through glass due to its permeable nature. Glass is a non-porous material, meaning that water cannot penetrate it or be absorbed by it.
If you lift the glass tumbler which is placed over a burning candle to 1cm height what hapens?
Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
Why can't we keep our hand above a candle flame?
Keeping your hand above a candle flame causes the heat to rise and can lead to discomfort or even burns due to the high temperature. The heat from the flame radiates outwards and can easily cause injury if your hand is too close.
Does light go through glass or reflect?
Light can both go through and reflect off of glass. When light passes through glass, it is transmitting through the material. However, if the angle of incidence is steep, light can reflect off the surface of the glass.
Why does the candle flame goes out when placing a glass over it?
When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.
What is the flame spread rating for glass?
Glass does not burn or contribute to flame spread, so it typically does not have a flame spread rating.
Does the flame from glass fire pits burn in colors of the glass?
well not usually when you keep trying your best to make the flame from glass fire pits burn in colors of the glass
Is it possible to get an iPod Touches glass replaced?
Yes go on Internet and search waterer g u have touch screen replacements
Why is the sodium flame is not visible through the cobalt glass?
The cobalt glass absorbs specific wavelengths of light, including those emitted by the sodium flame. This absorption of light by the cobalt glass results in the sodium flame not being visible when viewed through it.
What is the colour of sodium and potassium flame through a cobalt glass?
The flame color of sodium through a cobalt glass appears yellow, while the flame color of potassium through a cobalt glass appears lilac or pale violet. The cobalt glass filters out certain colors, allowing specific wavelengths to pass through, which affects the observed flame color.
How can a sun light a flame?
magifing glass
Why glass rods are used for flame tests in inorganic qualitative analysis?
Glass rods are used in flame tests for inorganic qualitative analysis because they are inert and do not react with the chemicals being tested. This ensures that the observed flame color is only due to the metal ions present in the sample. Additionally, glass rods are transparent, allowing for better observation of the flame color.
How is light affected when passing through water?
Light is affected by everything it touches. If it touches a glass of water, it *refracts* (bends).
What illegal drug leaves your finger black?
smoking crack bc of the "chore boy" copper that is used at the end of the glass pipe is usually pushed out and re-rolled to get the black stuff out of bad quality crack, usually excess baking soda bc the person was too lazy or incompetent to recook the crack to purify it. or the person uses the lighter on the glass pipe itself and the flame that touches that part of the glass leaves a black part. The person will often push the chore boy copper part to the other side and uses the pipe the other way around. also, meth pipes too if the person is using a regular lighter and touches the bowl, which previously had the flame on it.
Can not get pilot light to light on the fireplace?
If holding the controls in the LIGHT position for about 15-30 seconds does not keep your pilot lit, there is probably a problem with the thermocouple. That is the small tube that the pilot flame touches. Be sure it is not bent, and being missed by the pilot flame. They do go bad, and require replacement.
