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.
During boiling, the supplied heat energy is used to break the hydrogen bonds between water molecules rather than increase the temperature. This causes the temperature to remain constant at the boiling point until all the liquid has been converted to gas.
As 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.
because liquids have constant boiling points which cancel the effect external and internal pressure ..
When a pure substance changes state all of the energy goes into breaking (or reforming) the bonds. This means that the temperature remains constant.

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.

When water is heated the temperature eventually reaches a constant value and forms a plateau on the graph what does the plateau indicate?
The plateau on the graph indicates that the water has reached its boiling point. During this phase, the temperature remains constant because the heat energy supplied is being used to convert the liquid water into water vapor, rather than increasing the temperature.
The what remains constant when a liquid reaches boiling point?
The temperature of the liquid remains constant when a liquid reaches its boiling point. As the liquid absorbs heat, the energy is used to break the intermolecular forces between the molecules rather than increasing the temperature. Once all the liquid has vaporized, the temperature will start to rise again.
Is the water boiling temperature constant if the heater temperature increased 110 C?
yes
What can you notice about the temperature of sea water during boiling?
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
What is boiling point in science?
during boiling,the temperature of a mixture is different at different times. during boiling,the temperature of a substance changes at the start then it becomes the same and constant.
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.
Why is the temp of boiling pure acetone constant?
The temperature of boiling pure acetone is constant because during boiling, the heat energy is used to overcome the intermolecular forces holding the acetone molecules together, rather than raising the temperature. This results in a phase change from liquid to gas at a constant temperature until all the liquid acetone has vaporized.
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.

The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
