That is an oxymoron. Like jumbo shrimp or military intelligence.

What is difference between vapor pressure and vapor density?
I do not now
When recharging a refrigeration system with R-11 what vapor pressure is necessary in the shells before charging with liquid?
21.1" vacuum
What is the boiling point of water in space?
The boiling point of a liquid is the temperature where the vapor pressure is equal to the atmospheric pressure. Vapor pressure increases with temperature, as you heat the water up the vapor pressure keeps increasing until it matches the atmospheric pressure, then it is boiling. Space isn't quite a perfect vacuum, so the boiling point wouldn't be 0, but it would be very very low.
What are the advantages of vacuum distillation?
Doesn't require as much pressure as Reverse Osmosis and is therefor cheeper. Also the permeate is removed as a vapor which can be useful
Are variables in evaporation?
For evaporation from a pure water surface, the rate of evaporation is proportional to the difference in vapor pressure between that of the water surface and that of the bulk air over it. The vapor pressure of water in turn depends on its temperature.

Difference between pressure gauge and vacuum gauge?
A pressure gauge measures blow, a vacuum gauges measures suck
What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
Is a vacuum a force?
a vacuum is simply an empty or almost empty space. The forces that are apparent with vacuums are due to a pressure imbalance between the inside of the vacuum (low pressure) and the outside of the vacuum (high pressure) causing particles to want to migrate to areas of lower pressure. The effect of this pressure difference is often refered to as a vacuum force

The difference between vapor pressure of a pure solvent and its partial pressure?
vapor pressure of a pure solvent is the pressure needed for the gas to escape the pure solvent in vapor form. its partial pressure in this case will be the pressure of that escaped vapour (in the mixture of air). in simpler terms vapor pressure describes a single condensable system (just the vapor of the solvent and the liquid state of the solvent) while its partial pressure describes the multicomponent system (air). they are essentially the same thing describing different systems

What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.

What will a hydrate do if its vapor pressure is higher than the vapor pressure of the water vapor in the air?

Ether at room temperature is placed in a flask connected by a rubber tube to a vacuum pump the pump is turned on and the ether begins to boil why?
Because the pressure of the atmosphere in the flask is lowered by the vacuum; a liquid will reach it's boiling point when the pressure of the atmosphere is equal to or less than the vapor pressure of the liquid.
