Why does temperature remain constant during the boiling of water although is supplied?
The boiling water at its boiling point uses the extra energy being supplied to transform its state from liquid to gas (steam) at the rate of 540 cals per gram.
Now if you have the water boiling in a pressurized vessel you can make the water boil at a higher temperature and this is used in certain applications but the temperature will remain constant at that pressure as long as there is water to be converted to steam.

JordanAs a liquid is heated that energy is translated into kinetic energy of the molecules. At boiling point the kinetic energy of the hottest molecules is sufficient to drive them off into the gaseous state.
As more energy is added, more molecules are driven off. This carries large amounts of energy away, leaving the temperature of the liquid unchanged.
The temperature will not rise until all liquid has entered the gaseous state.

Does the temperature of boiling water rise?
It doesn't because during boiling, the temperature remains constant and so does the kinetic energy of the molecules. The latent heat supplied is used to do work against intermolecular forces of attraction while separating molecules such that the molecular potential energy increases. Some energy is also used to do work in pushing back the atmosphere.
What is the term used to describe the constant temperature at which a pure liquid changes to vapour?
Boiling point
Boiling liquid maintains a constant temperature?
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
How may it be checked that the liquid is boiling at a constant rate?
To check if a liquid is boiling at a constant rate, observe the bubbles forming in the liquid. If the size and frequency of bubbles are consistent, it indicates a constant boiling rate. Additionally, monitoring the temperature can help ensure a steady boiling process.
Why does the temperature qoes down when it reaches the boiling point?
When a substance reaches its boiling point, the energy supplied to the substance is used to overcome the intermolecular forces holding the substance together rather than increasing the temperature. This causes the temperature to remain constant until all the substance has turned to vapor.
