Question

What happened to the fire in the burning candle and paper when it was covered with drinking glass ?

Answer 1

The burning candle produces carbon dioxide and water in the form of water vapor. The glass becomes foggy due to this water. The flame goes out, of course, from a lack of enough oxygen in the glass. ... The water is pressed into the glass by the greater external air pressure

Answer 2

The glass becomes foggy due to this water to the fire in the burning candle and paper when it was covered with drinking glass

Explanation:

The water vapour produced by a burning candle contains carbon dioxide and water. Because of the water, the glass becomes foggy. Of course, the flame goes out since there isn't enough oxygen in the glass. The larger external air pressure presses the water into the glass.

Fire in the burning candle:

• The heat of the flame melts the wax around the wick when you light a candle. By capillary action, the liquid wax is drawn up the wick.
• The flame's heat vaporises the liquid wax (turning it into a hot gas) and begins to decompose the hydrocarbons into hydrogen and carbon molecules.

Paper when it was covered with drinking glass:

• The wick is lit by oxygen, which is the wax's fuel. The oxygen supply is cut off when the candle is closed with the glass jar.
• Initially, the candle burns by utilising the oxygen within the glass, but when the glass becomes depleted of oxygen, the flame gradually fades out.
