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.
Why burning candle goes off when it is covered by glass cup?
A burning candle goes off when covered by a glass cup because it uses up the available oxygen in the cup, creating a sealed environment with no oxygen for the flame to continue burning. This causes the flame to extinguish due to the lack of oxygen needed for combustion.
How can glass clean itself?
Certain types of glass, like self-cleaning glass, have a special coating that is hydrophilic, which means it attracts water. When it rains, the water forms a thin sheet on the glass, carrying away dirt and debris as it runs off. This helps to keep the glass looking cleaner for longer periods of time.
How do you get candle wax off of silver candlesticks?
One method to remove candle wax from silver candlesticks is to place the candlesticks in the freezer for a few hours until the wax becomes brittle. Then, gently scrape off the wax using a plastic scraper or your fingernail. Alternatively, you can use a hairdryer to warm the wax and then wipe it off with a soft cloth.
Why do candles go out when you put a beaker over it?
As we know that for an object or substance to burn, its by means of carbon. Fire is very complex and needs oxygen for it to burn so by putting a beaker over a candle you are actually cutting the consumption of oxygen by fire, which will stop the fire from burning. THAT ANSWER IS FALSE. Because the candle is under a beaker and most beakers have lips the beaker is not fully cut off from oxygen so there is still oxygen. The candle does go out because of the carbon dioxide that is in the beaker

Can candle wax come off glass cups so they can be drinkable?
Heat them up. You shold be able to pry it off with your fingers.
Why does the light of the candle turn off when the cup cover the candle and the water raises?
the candle light turns off when the cup is placed over the candle and water rushes in due to atmospheric pressure . when cup is placed on the candle all the air goes out and the glass lifts up due to the atmospheric pressure releases from outside of the cup as there is no air inside to balance the pressure exerted out of the cup . thus when the glass lifts up and the water gets into the cup .
Why burning candle goes off when it is covered by glass cup?
A burning candle goes off when covered by a glass cup because it uses up the available oxygen in the cup, creating a sealed environment with no oxygen for the flame to continue burning. This causes the flame to extinguish due to the lack of oxygen needed for combustion.
What experiment could you do to prove that oxygen is needed for burnig?
simply cover a burning candle with a glass to cut off the air, then the candle will burn out

Thin-film interference occurs when one clean glass plate it placed on top of another glass plate What does the thin film consist of in this case?
In this case, the thin film consists of the air gap between the two glass plates. When light reflects off the top surface of the top glass plate and the bottom surface of the bottom glass plate, interference patterns are created due to the difference in optical path lengths caused by the varying thickness of the air gap.
When a glass jar is placed over a lighted candle why the flame goes off?
When a glass jar is placed over a lighted candle, the flame eventually goes out due to a lack of oxygen. The candle burns oxygen to sustain the flame, and as the jar seals it off, the available oxygen inside the jar is consumed. Without sufficient oxygen, the combustion process cannot continue, leading to the extinguishing of the flame. Additionally, the heat from the flame warms the air inside the jar, causing it to expand and create a slight vacuum, further limiting oxygen supply.
What Is a thin glass wire that transmit light?
A fiber optic cable is a thin glass wire that transmits light signals to carry data over long distances. The light signals travel through the core of the cable by constantly reflecting off the walls of the glass. Fiber optics are commonly used in telecommunications and networking for their high speed and efficiency in transmitting data.
