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
the pressure decreases the pressure increases
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.
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.
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.
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.
density decreases as air pressure increases
As altitude increases, atmospheric pressure decreases.
As you go above sea level, the atmospheric pressure decreases, and so the boiling point also decreases to below 100ºC.
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
increases
Pressure decreases.
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.
Pressure decreases
The temperature decreases the higher you go.
The speed increases and the pressure decreases.
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.
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.
