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.
When a liquid sits, because of the laws of kinetics, some of the liquid's molecules at the very top escape and become gaseous molecules. This gas exerts a force of pressure on the liquid, and this is known as vapor pressure.
Vapor pressure is the pressure produced when vapor particels above a liquid in a sealed container, collide with the container walls.

Earth turns the wind to the right, resulting in the counter-clockwise wind flow
True vapor pressure (TVP) is a measure of the volatility of petroleum distillate fuels. It is said to be the pressure of the vapor in equilibrium with the liquid at 100 F.
Vapour pressure is the pressure exerted on the liquid surface by vapour that forms a vacuum created when air space is left above the liquid surface
The vapor pressure is the pressure - at thermodynamic equilibrium, in a closed system, at a given temperature - exerted by vapors on the liquid or solid.
A difference in pressure
That is correct.
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.
At higher temperature the vapor pressure is higher.
The lowering of the vapor pressure is a colligative property.
Osmotic pressure.
The vapor pressure of 1 m sucrose (C12H22O11) is higher than the vapor pressure of 1 m NaCl where the solvent is water Sea water has a lower vapor pressure than distilled water. The vapor pressure of 0.5 m NaNO3 is the same as the vapor pressure of 0.5 m KBr, assuming that the solvent in each case is water The vapor pressure of 0.10 m KCl is the same as the vapor pressure of 0.05 m AlCl3 assuming the solvent in each case is water The vapor pressure of 1 m NaCl is lower than the vapor pressure of 0.5 m KNO3, assuming that the solvent in each case is water The vapor pressure of 0.10 m NaCl is lower than the vapor pressure of 0.05 m MgCl2 assuming the solvent in each case is water.
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.
Vapor pressure of a liquid at its normal boiling temperature is simply the atmospheric pressure, aka 1 atm, 760 torr, etc. This is by definition.
A thermometer which utilizes a gas(vapor) to react to temperature changes for an accurate reading. (Instead of a hazardous material such as a mercury filled thermometer.)
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
At higher temperature the vapor pressure is higher.

In chemistry, the convergence pressure is a specific point where two component systems converge. These two systems usually have different liquid vapor equilibriums.
high pressure vapor
True Vapor Pressure is the pressure of the vapor in equilibrium with the liquid at 100 F (it is equal to the bubble point pressure at 100 F)
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure
