When heat is added to a liquid at the boiling temperature it converts the liquid into a gas at the same temperature because?

The additional heat, called "enthalpy" completes the phase change, by changing the arrangement of the molecules in the existing environment, not the temperature. The energy must be removed from a gas to cause condensation into liquid, and from a liquid to cause solidification (freezing). Conversely, it is added when changing a solid to a liquid or a liquid to a gas. At a certain temperature (critical temperature), the process happens spontaneously because the phase boundary disappears.

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.
What is the temperature at which a liquid turns into a gas?
the temperature at which a liquid turns into a gas is called the boiling point.
When will the liquid boil?
When the temperature reaches the correct temperature (boiling point).
Liquid alcohol will change to vapor when its temperature reaches the what?
Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C
What occurs when a gas turns into a liqiud?
first the liquid has to be heated to its boiling point (every element has a different one) then heat makes the molecules more spaced and moving around faster (heat is energy) and it becomes a gas
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.
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.
The temperature at which a liquad becomes a gas is the freezing or boiling point?
The boiling point, because a liquid boils into a gas.
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 is the temperature at which a liquid turns into a gas?
the temperature at which a liquid turns into a gas is called the boiling point.
Why does water exist in liquid state?
At room temperature, water is in a liquid state because it has a high boiling point, as compared to gases that have relatively low boiling points.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
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.
Why is mercury liquid at room temperature when cadmium isn't?
It is liquid because it has a low melting point and a low boiling point.
The conversion of a liquid to a gas below the boiling point?
A liquid can convert to a gas at a temperature below the boiling point because the boiling point is recognized to be a property at standard pressure. At a lower pressure a liquid may boil off at a temperature much lower than the standard boiling point.
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
