An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.

Why do compounds with strong intermolecular attractive forces have higher boiling points than compounds with weak intermolecular attractive forces?
Heat is simply an expression of how fast molecules are vibrating and moving about, for the purposes of state of matter. Intermolecular bonds are what stop this motion from happening, so the stronger this bond, the higher the temperature needs to be for the compound to melt or boil.
Why must the lid be sealed when lavender flowers are heated in a container?
To stop water vapour escaping
What effect do glass beads have on the boiling point of water?
bringing water to boil is effective in killing or inactivating most bacteria viruses and pathogens .according to the wilderness medical society water temperatures above 160 degree kill all pathogens
Why should you stop collecting the distillate when temperature rises above 78 degrees celsius in fractional distillation of alcohol?
Because above 78 degrees C you will start collecting liquids that have a higher boiling point than alcohol. Once the temperature of the vapour goes up you know you have collected all the alcohol from the sample.
The pressure needed to stop osmosis is?

Why Stop boiling water Vacuum Chamber With the continuation of the vacuum pump work And vacuum pressure gauge -30 in hg Thank you?
You want to stop boiling water Vacuum Chamber because of the vessel seal. If the pump is boiling it will stop at the point of equilibrium.
Where is valve located to increase water pressure?
There is no such thing as a valve cannot increase or decrease pressure IT can throttle volume or stop the flow.=One would need a pressure booster pump to increase pressure=
What happens to boiling water if the pressure increases or decreases?
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
Why boiling point of water in Shimla in lower than that in Delhi?
It depends what your altitude is compared to sea level. The lower below sea level you are, the more atmospheric pressure there is thus increasing boiling point; pressure raises the boiling point. That is why your auto has a pressurized cooling system - to stop boil over.
How long can you drive whit a leaking problem with the water pump in a Solara 2.4 2004?
You should stop driving immediately since you are bound to overheat. Water under pressure increases boiling point. With no pressure-you may have trouble since it is now normal boiling point.
When road surfaces become slippery you should Use cruise control Decrease the tire pressure Increase following distance Increase the tire pressure?
Increase your following distance. It will take you longer to stop. Slowing down is also a really good idea.
How can we avoid surge in springs?
Keep a steady pressure on the brakes. Do not release too soon when coming to a stop. Brake far in advance of a stop and increase your following distance.
How does awc work in compression machine?
set the machine as per the standard wt. & acquire the pressure . this will be the reference pressure. then increse the wt. & decrease the wt. & acquire the pressure. then calculate the % increase or decrease pressure with respect to the reference pressure. this will give HIGH EJECTION PRESSURE & LOE EJECTION PRESSURE. The high stop & low stop pressure can be seleted considering the punch pressure suggested by the manufacturer. generally this 3/4 th of the suggested pressure.
Does blood pressure increase when the heart relaxes?
Nope. The blood pressure actually decreases when your heart relaxes. Although the heart relaxes, it is still in pressure or else your blood would stop flowing which to some people is a bad thing.

After Felix adds salt to the boiling water what will he have in the pot?
Salt water, but the water will stop boiling because upon adding the salt it raised the boiling point of water.
