Is it true that the boiling point of a liquid remains constant at all altitudes?

No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.

Why a fresh cup of tea made with boiling water is not as hot at higher altitudes as it is at sea level?
Because, water boils at lower temperatures at higher altitudes, because there is less air pressure pushing down on the liquid to prevent it from boiling and be released into the air.
Why would the temperature of a liquid remain constant when heat is continuously being added?
A temperature at which internal pressure become equal to atmospheric pressure is called boiling pointAt boiling point kinetic energy of liquid molecules remains constant ,although heat is continously supplied that is why boiling point of a liquid remains constant.
How are fluid preassure related to the motion of a fluid?
There is a theory called Bernoulli's Theorem which states that: p+dv2/2 +dgh=constant, where p stands for pressure d for density of the fluid g the acceleration due to gravity h the height of th liquid from the base level and v the speed of the liquid. If the pressure throughout the liquid remains constant then the velocity also remains constant. On changing the pressure the velocity also changes to keep the equation value constant.
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.
Relation between atmospheric pressure and boiling point?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Is that true that boiling point of a liquid remains constant at all altitudes?
The boiling point is lower at high altitude.
Is it true that boiling point of a liquid remains constant in all altitudes?
No. The higher the altitude the more difficult, and fuel expensive, to boil water.
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 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.
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 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.
When the liquid as a constant boiling point is it pure or not pure?
All pure liquids, such as water, H20, have constant boiling points at certain atmospheric pressures, which is helpful in determining the identity of an unknown liquid. Some liquids have constant boiling points that are not pure, such as nail polish remover, or ethyl acetate. Since it is a mixture of more than one pure liquid, it is not a pure liquid itself, but if always mixed in the same ratios, will have a constant boiling point.
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.
Which term is defined as the change in physical state form liquid to gas occurring throughout liquid?
The change in physical state from liquid to gas occurring throughout the liquid is called boiling. It occurs at boiling point of a liquid or when the pressure of the surroundings is reduced as per its boiling point. It boils with the use of vacuum pump and at high altitudes. Boiling Vaporization is the change in state from a liquid to a gas. Evaporation and boiling are the two types of vaporization. You are describing boiling. boiling A+: Condensation
The reduced vapor pressure at high altitudes causes a liquid to boil at a?
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.
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.
When does liquid water turn to gas?
At sea level, liquid water boils and becomes a gas at 212º F, or 100º C. Due to lower surrounding pressure it has a lower boiling point at higher altitudes (ex. boiling point is 202º F in Denver, CO, about 5,000ft. above sea level), and a higher boiling point at lower altitudes.
