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.

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 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.
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.
Why is temperature of boiling water cannot be measured using an alcohol thermometer?
Because the alcohol boils at a lower temperature than water.
Why butane is easy to undergo a change in phase?
Because its Boiling point is closer to normal room temperature.
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.
A boiling liquid maintains a constants temperature because?
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.
What do you notice about its temperature during boiling?
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.
What will happen to the temperature of a pot of boiling water as the water evaporates?
As water evaporates from the boiling pot,its temperature drops.This results from the fact that water molecules during evaporation extract its latent heat of vapourization from the pot, thereby exerting a cooling effect on it and its content.Regulation of body temperature by sweating is based on this principle. When sweat comes out of its pores, usually in suny days, it evaporates and in the process extract its latent heat of vapourization from the body.This causes the body temperature to decrease.In this way it keeps the body temperature fairly constant.
Why does the temperature of a substance remain constant during it's melting point on boiling point?
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
Why is the temp of boiling pure acetone constant?
Acetone has a constant boiling point because it is an azeotrope. Azeotropes are mixtures of two or more liquids whose proportions cannot be altered by simple distillation. They are also called constant boiling mixtures.
Which is hotter the boiling water or oil?
Boiling oil because it boils at a higher temperature
Why does temperature remains constant during the process of melting or boiling?
This is because the heat supplied to the substance is used up in the overcoming the inter molecular forces and therefore , it does not show up as a rise in the temperature. Temperature stays constant until all the interactions are broken.
Why does temperature remain constant during melting and boiling?
because of phase transtion i.e. from solid to liquid during melting and from liquid to vapour during boiling. so just to change over from one phase to the other heat is totally utilized.
Does the water temperature change as it boils?
If you heat water its temperature will increase until it reaches 100 degrees C, at which point it starts to boil. Boiling means it is all changing into a gas. Whilst it is boiling, the temperature remains constant, because the energy is being used to separate the particles instead of making them move faster. Not until the liquid has become gas does the temperature rise again.
