Vapor pressure and evaporation are related but not the same thing. Evaporation is the process by which a liquid turns into a gas at a temperature below its boiling point, while vapor pressure refers to the pressure exerted by the vapor of a substance in equilibrium with its liquid phase at a given temperature. Evaporation contributes to the generation of vapor 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.
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
Vapor pressure is related to the boiling point because the boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. When the vapor pressure of a liquid reaches the same pressure as the surrounding atmosphere, the liquid will boil and turn into a gas.
If a liquid and gas are in equilibrium, it means that the rate of evaporation is equal to the rate of condensation. This indicates that the system has reached a balance between the liquid and gas phases with no net change in the amount of substance transitioning between the phases.
Diethyl ether has a higher evaporation rate compared to n-butyl acetate due to its lower boiling point and higher vapor pressure. This means that diethyl ether will evaporate more quickly than n-butyl acetate when exposed to the same conditions.
Water vapors are products of evaporation.
Well you don't because when water evaporates its a water vapor and a water vapor you can't see and that's the very same thing.
liquid becomes gas because as the liquid is heated it starts to get a lot of kinetic energy as it is turning into gas the molecules start to move rapidly in any direction and has no fixed shape
Well Vapor And Steam Are The Same Thing,In That Case It Would Be Evaporation Since Vapor/Steam When Liquid Turns Into A Gas :)
The vapor pressure of pure water will be higher than that of an aqueous solution of sodium chloride at the same temperature because the presence of sodium chloride reduces the number of water molecules available to evaporate, lowering the vapor pressure of the solution. In other words, the solute particles in the solution interfere with the evaporation of water molecules, resulting in a lower vapor pressure compared to pure water.
Transpiration is the evaporation of water from plants and tree. I would assume that it is the same thing. It wouldn't matter what is evaporated first because either way something is being evaporated.

The Steam and Vapor are the same thing i.e. Water in its gaseous state. However Steam is formed by Forced Boiling and is at a pressure greater then the atmospheric pressure as used in a Steam Engine. Water Vapour is free conversion of Water from Liquid to Gaseous Stage thru evaporation. It is in approximate equilibrium with atmospheric pressure Steam is formed by by raising the Temperature (giving heat energy) of water above its Boiling Point i.e. 100 deg Celsius whereas evaporation of water (from water bodies) may occur at temperature way below the boiling point i.e. 30 deg Celsius. Drying of washed clothes is an example
No, true vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase at a given temperature. Absolute pressure refers to the total pressure within a system, including atmospheric pressure. These two concepts are related but not the same.
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
