In that case the water pressure is not reduced, but rather, the vapour pressure of the water is increased by means of heating.

Unlike relative humidity, vapour pressure deficit has a simple nearly straight-line relationship to the rate of evapotranspiration and other measures of evaporation.
43.
Cold weather can cause problems with this system, reducing the vapour pressure and increasing the chance for liquefied gas to be drawn into the marker.

The dipole moment of methyldiborane is 0.56 D . It has a vapour pressure of 61 mm Hg at-77.2 �C.
45.
The system is usually baked, preferably under vacuum, to temporarily raise the vapour pressure of all outgassing materials in the system and boil them off.
46.
All materials, solid or liquid, have a small vapour pressure, and their outgassing becomes important when the vacuum pressure falls below this vapour pressure.
47.
All materials, solid or liquid, have a small vapour pressure, and their outgassing becomes important when the vacuum pressure falls below this vapour pressure.
48.
Ultra-high vacuum systems are usually baked, preferably under vacuum, to temporarily raise the vapour pressure of all outgassing materials and boil them off.
49.
Another use for lute was to act as a safety valve, preventing the buildup of vapour pressure from shattering a vessel and possibly causing an explosion.
50.
Unsymmetrical dimethyldiborane melts at-150.2 �C . Vapour pressure is approximated by Log P = 7.363-( 1212 / T ).
