as the temperature increase the liquid becomes less condensed and the pressure decreases. as its molecule lossen they move faster, the liquid will turn into a gas. if the temperature decreases then it will do the opposite. it would slow down the molecules, and increase the pressure, making a 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.


What factors affect the vapour pressure of a liquid?

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


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.


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 the liquid boils when its vapor pressure becomes equal to ATM pressure?

When the vapor pressure of a liquid equals the atmospheric pressure, the liquid molecules are escaping the liquid surface as quickly as they are returning, causing the liquid to boil. This is because the vapor pressure represents the point at which the liquid and gas phases are in equilibrium and the liquid can transition to a gas phase.

What kind of pressure of a liquid is the pressure exerted at equilibrium and is dependent on temperature only?

Vapour pressure ; yes


What is the effect of the temperature on the vapour pressure?

When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.


What is the vapour pressure of liquids?

Vapour pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. It is a measure of a liquid's tendency to evaporate. The higher the vapor pressure, the more volatile a liquid is.


How can I define boiling point scientifically?

Boiling point is defined as the temperature at which the vapour pressure of a liquid is equal to the atmospheric pressure. In other words, it is the minimum temperature at which a matter which is in the liquid state gets converted to a matter in the gaseous or vapour state.


How will show that the process of evaporation depends on the nature of the liquid?

By the measurement of the pressure vapour at a given temperature; this value is different from liquid to liquid.


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.


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.


What is the saturation temperature of vapour or the boiling temperature of a liquid?

The saturation temperature of a vapor is the temperature at which it condenses to a liquid at a given pressure. It is also known as the boiling temperature of a liquid, as it is the temperature at which the vapor pressure of the liquid equals the surrounding pressure, resulting in boiling.


What halogen has a deep brown vapour?

Bromine. This is a liquid at room temperature and pressure but fumes a rich reddy brown vapour. Keep it in a fume cupboard.
