vapour pressure

Figure 3.13 shows how the vapour pressure of water increases with temperature.

This occurs when a sample has a high vapour pressure.

This is the vapour pressure curve of water (see figure 3.13).

The more volatile component is thus the one with the higher vapour pressure.

The rate of loss is related to the difference between the water vapour pressure inside the produce and in the air.

Mention is also made of vapour pressure. These are very technical matters.

All solids have vapour pressures although they tend to be very low.

The difference in vapour pressure between the hot and cold side helps to push water molecules through.

Materials which are not allowed due to high vapour pressure:

The liquid mixture thus has a higher vapour pressure.

The partial vapour pressure of the less volatile component decreases at the same time.

The molecules are consequently held back in the liquid phase and the vapour pressure is lower.

Any fluid can be used, but mercury is preferred for its high density and low vapour pressure.

In countries with warm summers, volatility increases and therefore vapour pressure will have to be increased.

This is hypothetical since in reality all solids exert a vapour pressure although it may be very small.

White phosphorus has an appreciable vapour pressure at ordinary temperatures.

It was inflated with liquid rubber monomer under its own vapour pressure.

The curve ST represents the vapour pressure of water below its freezing point.

In this case the vapour pressure of the solution is almost entirely due to the solvent particles.

These compounds have relatively high vapour pressures and are evacuated from the chamber during processing.

The increase in vapour pressure with temperature can be explained in terms of the kinetic theory.

The strength of the produced vacuum is limited by the vapour pressure of the flowing water.

Meteorology uses vapour pressure or relative humidity to characterize atmospheric water.

Excessive vapour pressure is released automatically through safety valves.

The pressure exerted by these escaping particles is called the vapour pressure of the liquid.
