Answer:
Q 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. If the air in the glass cools down and its volume decreases, a negative pressure is created inside the glass.
This happens because oxygen inside the tumbler is utilised and burning the candle. all the oxygen inside the tumbler gets converted into carbon dioxide.Carbon dioxide does not support burning and hence candle stops burning.
Q2.
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
liquid bubble when they are heated because they are boiling. Boiling is the process through a liquid changes into a gaseous state. So, this bubbles could be formed by the highly energetic particlesof the liquid that are escaping into the atmosphere from the liquid surface.
