For a vapor bubble to expand, the temperature must be high enough that the vapor pressure exceeds the ambient pressure (the atmospheric pressure, primarily).

And when they escape into vapor, then they create a vapor pressure above here.

At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure.

Measurement and units Vapor pressure is measured in the standard units of pressure.

As the vapor pressure increases, the concentration of vapor of the flammable liquid in the air increases.

The normal boiling point of a liquid is the temperature at which the vapor pressure is equal to normal atmospheric pressure.

We found some non toxic refrigerants that worked at very low vapor pressures.

Mechanism Every liquid has a vapor pressure, which is a function of that liquid's temperature.

You have low blood pressure.

Experimental measurement of vapor pressure is a simple procedure for common pressures between 1 and 200 kPa.

Down at low altitude, we have high pressure and once we start getting towards outer space we have low pressure.

The pressure gradient between this region and the ambient pressure will propel matter toward the low pressure area.

Remember, everything with boiling deals with what's happening at the surface, and we talked about that in our vapor pressure.

Low pressure air rises from the equator and meets high pressure air from the poles.

And that's very different from having low blood pressure.

And then it's inflated with this low pressure air.

The force pushing the water towards the low pressure region is called the pressure gradient force.

Low velocity will result in lower or no pressure drop.

How do you have low blood pressure in your skin?

Low volume means a high pressure because those particles push back.

Simple explanation Sea water naturally wants to move from a region of high pressure (or high sea level) to a region of low pressure (or low sea level).

In a geostrophic flow, instead of water moving from a region of high pressure (or high sea level) to a region of low pressure (or low sea level), it moves along the lines of equal pressure (isobars).

Two booster stages were added to the LP (low pressure) compressor, which increased the overall pressure ratio to 29.3.

He had low blood pressure. He used to faint a lot, you know.

So air always wants to go from high pressure to low pressure and so air is going to flow into our lungs.

Seeds triggering the conversion of vapor are referred to as condensation nuclei, as in the case of water vapor.

And if that vapor pressure is high enough, you can almost view them as linemen blocking the way for more molecules to kind of run behind them as they block all of the other ambient air pressure above them.

When heating a liquid consisting of two or more components, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed.

As long as interest rates remain low, there is no downward pressure on public investment.

If there's a region of low pressure in the atmosphere, air is pushed toward it,

Hot humid air rose up to create several thunderstorms around an area of low pressure.

When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle.

The First Phase (1914 1921) Construction on the low pressure and machinery buildings began in 1914.

By vapor trail was over the right shoulder.

It was also during the 1960s that all the low pressure equipment was shut down and dismantled.

The storm then rapidly weakened into a remnant area of low pressure over southern Assam that evening.

Now for diastolic pressures, we know that diastolic pressures are the low range of a blood pressure.

A long term (more than 4 weeks) low sodium diet is effective in reducing blood pressure, both in people with hypertension and in people with normal blood pressure.

So when water molecules (water vapor) are added to a given volume of air, the dry air molecules must decrease by the same number, to keep the pressure or temperature from increasing.

This may include concentrating the product, formulation revision (i.e., addition of components to increase stability, preserve appearance, and or improve processing), decreasing a high vapor pressure solvent, or increasing the surface area.

With a large output gap and low inflationary pressure, expansionary policies show great potential for reviving economic activity.

Humidity is the amount of water vapor in the air.

And when this happens, it can cause areas of very low pressure, which results in the water literally vaporizing.

This combination eliminates the need for a separate low pressure hose for the BC, though the low pressure hose for the combined use must be larger than standard BC inflation hoses, because demand on it will be higher if it is used for breathing.

Closed cup testers normally give lower values for the flash point than open cup (typically lower) and are a better approximation to the temperature at which the vapor pressure reaches the lower flammable limit.
