water boils when the vapour pressure becomes equal to the external pressure. So if we increase the pressure, the rate of boiling will increase. Think of the vapor pressure as the pressure that is needed to force a bubble to the surface.
it lowers

What happens to the pressure of the earth as depth below the surface increases?

the pressure decreases the pressure increases


What happens to atmospheric pressure as altitude increase?

This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.


What happens to air pressure as the distance from Earths surface increases?

As the distance from Earth's surface increases, the air pressure decreases. This is because there is less air above pushing down on the air below. The decrease in air pressure is why it becomes harder to breathe at higher altitudes.


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

The boiling point of a substance decreases as you go higher above sea level because the atmospheric pressure decreases. At higher altitudes, there is less pressure pushing down on the liquid, causing it to boil at a lower temperature.


How does the air pressure change as the altitude increases?

As altitude increases, air pressure decreases. Gravity causes the atmosphere to become heavier the closer you are to the ground. The atmosphere may seem weightless but all the air molecules add up to a tremendous amount of mass. If you think of the atmosphere like blankets, the more blankets you have piled on you the heavier they become, thus pressing down on your body more and more. This is the same in the atmosphere, where the higher the altitude, the less overlying atmosphere, the less pressure on air molecules. At higher altitudes the air molecules have more freedom to move around.

What happens to atmospheric pressure as altitude increases?

As altitude increases, atmospheric pressure decreases.


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.


What happens to the altitude and boiling point as the pressure is increased?

As altitude increases, pressure decreases, so boiling point decreases, so the liquid would boil at a lower temperature and would not be able to get as hot and remain a liquid. As pressure is increased, boiling point increases, meaning the liquid could get hotter than normal and remain a liquid.PV=nRT - pressure x volume = the number of moles x constant x temperature

What happens to flow when pressure is increased?

Pressure decreases.


When boiler pressure increases what happens to the boiling point of water?

The boiling point of water is dependent on environmental factors and the presence of solutes. In this case the pressure of the system on the water serves to increase the boiling point of water. The higher pressures increase boiling points while lowering pressure decreases it.


What happens to the atmosheric pressure when the height above the surface of earth increases?

Pressure decreases


What happens to the boiling point of water at altitudes above sea level?

The temperature decreases the higher you go.


What happens to the fluid speed and the pressure between the two boats?

The speed increases and the pressure decreases.


What happens when pressure in a fluid changes?

When pressure in a fluid changes, the volume and density of the fluid may also change. If the pressure increases, the volume decreases and the density increases, leading to compression of the fluid. Conversely, if the pressure decreases, the volume increases and the density decreases, causing expansion of the fluid.


What happens to the boiling point of water at higher elevations where atmospheric pressure is less?

The boiling point of water decreases at higher elevations where atmospheric pressure is lower. This is because the lower pressure makes it easier for water molecules to escape into the air, requiring less energy to reach the boiling point.
