Water is a liquid. When you heat it, it moves around a lot faster. When the water reaches 100 degrees Celsius, it turns into a gas called water vapour.This gas is lighter* than the water around it, so it rises to the top. Then it escapes into the air. As more and more of the water turns into gas, more of it disappears into the air. After a while, every last drop of the water will be gone.
* Actually, the correct statement is that the gas is less dense than the water around it.
Most of the bubbles start at the bottom, because that's where the heat is. The more heat you apply, the more bubbles you will get. The water is turning into a gas very quickly, and lots of bubbles form, and all try to rise to the surface at once. They push the water out of the way as they rise, and jump out of the surface. This is what we call 'boiling water'.
So basically, the boiling point and below, the water stops moving so rapidly to produce bubbles.
When a liquid is boiling the temperature stays constant. This is because the heat energy you are adding is being taken away with the vapour being produced.
Pure water does not increase - or in any other way affect - the boiling teperature of water becasue the latter is normally taken to be that for pure water!The question does not make sense. What type of water is it whose boiling temperature is meant to be increased by pure water? Impure water?In any case, pure water does not increase the boiling point of water but lowers it.
Yes, the volume of water can affect the time taken for it to reach its boiling point. A larger volume of water will generally take longer to reach its boiling point compared to a smaller volume, as more energy is required to heat up a larger amount of water.
It takes a certain energy to convert water to steam. Any additional energy you supply to the water, as heat, will be taken away by water converting to steam. The maximum temperature of a liquid is its boiling point so water shows constant maximum temperature 100o Celsius (if it is pure).
i believe it is 25ºC

No, the quantity doesn't affect the temperature but it may (and usually does) affect the time taken for a substance to achieve that temperature.
There will be a sudden change in temperature and it is likely that the thermometer may even break.
During boiling, the amount of energy remains constant as the temperature of the substance stays the same until all of it has converted into vapor. Once boiling starts, the added heat energy is used to break the intermolecular bonds holding the liquid together, rather than increasing the temperature.
A temperature at which internal pressure become equal to atmospheric pressure is called boiling pointAt boiling point kinetic energy of liquid molecules remains constant ,although heat is continously supplied that is why boiling point of a liquid remains constant.
Evaporation is a cooling process because energy is required to break the bonds between liquid molecules. This energy is taken from the surroundings, resulting in a decrease in temperature. In contrast, boiling requires additional energy input to overcome the intermolecular forces holding the liquid together, leading to an increase in temperature.
A dissolved directorship means that a company has stopped trading. This is taken to mean that the company ceases to exist as a legal entity.
If its still a solid at room temperature then to melt it would have to be at a higher temperature than 20 degrees. If its still a solid at room temperature then to melt it would have to be at a higher temperature than 20 degrees.
That would mean microbes are growing in the soup. It indeed could be dangerous. Don't eat it.

The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.
Bubbling in swimming refers to exhaling air through your nose while under water. This takes place after you have taken a breath above water and then placed your face beneath the surface to continue swimming. It helps to regulate your breathing patterns under the water.
