Define vapour pressure of a liquid.

If P_(A) is the vapour pressure of a pure liquid A and the mole fraction of A in the mixture of two liquids A and B is x, the parial vapour pressure of A is:

The temperature at which the vapour pressure of a liquid equals external pressure is called

The temperature, at which the vapour pressure of a liquid becomes equal to the atmospheric pressure is known as

Explain the term vapour pressure. How is vapour pressure of a liquid influenced by altitude ? Discuss ?

The vapour pressure of a pure liquid A is 40 mm Hg at 310 K . The vapour pressure of this liquid in a solution with liquid B is 32 mm Hg . The mole fraction of A in the solution, if it obeys Raoult's law, is:

The vapour pressure of a pure liquid A is 40 mm Hg at 310 K . The vapour pressure of this liquid in a solution with liquid B is 32 mm Hg . The mole fraction of A in the solution, if it obeys Raoult's law, is:

The vapour pressure of a pure liquid A at 300 K is 150 torr. The vapour pressure of this liquid in a solution with a liquid Bis 105 torr. Calculate the mole fraction of A in the solution if the mixture obey's Raoult's law.

The highest temperature at which vapour pressure of any liquid can be measured is

The vapour pressure of a pure liquid at 25^(@)C is 100 mm Hg. Calculate the relative lowering of vapour pressure if the mole fraction of solvent in solution is 0.8.

The vapour pressure of a liquid in a closed container depends upon (1) temperature of liquid (2) quantity of liquid (3) surface area of the liquid
