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 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 is the term used to describe the constant temperature at which a pure liquid changes to vapour?
Boiling point
Does the temperature of a boiling liquid increase as it boils?
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
What are the signs that a liquid has reached its boiling point?
Oh come one -_-''Its obviousBubbles of vaporised liquid will formThe temperature of the liquid when boiling will remain constant even when more heat is applied.As the liquid is heated, the vapour pressure increases until it equals the pressure of the gas above it.
What is it called the temperature at which a liquid boils?
It is the Boiling point.
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.
The what remains constant when a liquid reaches boiling point?
The temperature. A liquid will increase in temperature until it reaches the boiling point temperature. At this temperature the liquid will become a gas. Under normal circumstances, the liquid cannot get any hotter than the boiling point without becoming a gas. So the liquid remains the same temperature until it has all boiled away.
Boiling liquid maintains a constant 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 is the term used to describe the constant temperature at which a pure liquid changes to a vapour?
Boiling point
What is the term used to describe the constant temperature at which a pure liquid changes to vapour?
Boiling point
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.
Briefly describe two methods or techniques for the determination of boiling point?
Distillation - where the constant tempreature of the vapor given off when boiling the liquid at the lowest temperature possible is recorded as the boiling point. Capillary Bell - where the temperature, under pressure, that the liquid enters the bell in place of the vapor is recorded as the boiling point of the liquid.
What happen to the temperature boiling water as it's boil?
When water is boiling, the temperature remains constant, as the energy it is absorbing is being used to change the liquid water into water vapor.
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.
What happens to the temperature of a liquid as it changes from a liquid to a vapor?
The liquid vaporizes and the temperature increases as the volume also increases.
When atmospheric pressure increases what happpens to the boiling temperature of a liquid?
The boiling temperature of a liquid increases as the gas pressure a the liquid's surface increases.
What happen to the temperature when ice is heated?
During a phase change (from solid to liquid, as in melting and also from liquid to gas as in boiling) the temperature remains constant, as all of the energy is going to affecting the change, rather than raising the temperature. Once it has changed from solid to liquid, the liquid can then raise in temperature.
