What happens to the boiling point of a substance when you go higher above sea level?

The boiling point of water will decrease. At high altitudes, air pressure is lower, so it is easier for the water molecules to "escape" into the air as gas molecules.

Does freezing temperature change at higher altitudes?
Elevation has minimal affects on the freezing point of water as it doesn't deal with gas molecules as boiling does. Elevation affects the boiling point of water because the air pressure changes with elevation.
Is water vapor gas above boiling water?
it is above
Are melting and boiling points of a substance the same?
The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".
What is the effect of a soluble and nonvolatile impurity on the boiling point of a liquid?
The presence of a non-volatile solute in a solution increases its boiling point. The amount of the elevation of the boiling point depends only on the number of molecules of solute present, and not on their identity. See the article entitled "Boiling-point elevation" on Wikipedia for the maths involved.
What will happen to a liquid when it is heated above its boiling point?
That depends how much you heat it.If you heat it no higher than its boiling point, it will become a hot liquidIf you heat it above its boiling point, but not above its critical point, it will become a vapour.If you heat it above its critical point it will become a gas.What_does_a_liquid_become_when_heated_up
What happens to the boiling point of water at altitudes above sea level?
The temperature decreases the higher you go.
How can the temperature in the autoclave go above boiling temperature of 212 F?
At higher pressure the boiling point is higher.
What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
Does boiling have a liquid change into a gas?
Boiling is one of the processes by which a liquid changes into a gas. It occurs when the substance is at or above its bowling point.
What happends to the boiling point of a substance when pressure above it decreases?
The boiling point will also decrease in this case.
What happens at a liquid's boiling point?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it.
Does boiling point of water change as you move above sea level?
yes the boiling point changes with elevation. the higher the elevation the lower the boiling point.
What happens to boiling point above sea level?
As you go above sea level, the atmospheric pressure decreases, and so the boiling point also decreases to below 100ºC.
How can the temperature in the autoclave go above the boiling point of water?
Because the pressure is higher.
How do you lower a substance's boiling point?
by lowering the air pressure above it. that's why things boil faster the higher you are (higher elevations compared to lower elevations). you can actually boil water at room temperature by putting it in a container and sucking the air out of it. its kinda neat.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
How can water in an engine stay a liquid when the temperature is above its normal boiling point?
The cooling system is pressurized and requires a higher temperature to reach boiling.
