Vapor pressure or equilibrium vapor pressure are the pressure of a vapor in thermodynamic equilibrium with its condensed phases in a closed bottle. All liquids and solids have a tendency to evaporate into a gaseous form, and all gases have a tendency to condense back to their liquid or solid form.
The equilibrium vapour pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile

How does adding a solute affect the vapor pressure?
Adding a solute in a liquid the vapor pressure is lowered.
Which of the following factors affect the vapour pressure of a liquid?
Type of molecule: intermolecular forces between molecules are: * relatively strong, the vapor pressure will be relatively low. * relatively weak, the vapor pressure will be relatively high. Temperature: * higher temperature, more molecules have enough energy to escape from the liquid or solid. * lower temperature, fewer molecules have sufficient energy to escape from the liquid or solid.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Why the relative lowering of vapour pressure is independent of temperature?
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.
Vapor pressure results from?
pressure of gas over its liquid equilibrium
How does adding a solute affect the vapor pressure?
Adding a solute in a liquid the vapor pressure is lowered.
When smelling a liquid?
When this liquid has a great vapour pressure.

What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Does vapour pressure depend upon the nature of a liquid?
because nature of liquid means a attractive forces less attractive forces means low vapour pressure
What will be happen if liquid other than water are used in variation of pressure with depth?
it depends on the vapour pressure of the liquid
Why the relative lowering of vapour pressure is independent of temperature?
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.

Why evapourate at a low pressure?
Reducing the air pressure allows the molecules to escape
What kind of pressure of a liquid is the pressure exerted at equilibrium and is dependent on temperature only?
Vapour pressure ; yes
What is vapour binding?
when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.
