Identify which liquid will have a higher vapour pressure at `90^@`C If the boiling point of two liquids A and B are `140^@` C and `180^@` C, respectively.

What is the effect of pressure on the boiling point of a liquid ?

What is the effect of increase in pressure on the boiling point of a liquid ?

Why does the boiling point of liquid rise on increasing pressure ?

Out of the four liquids given below, the one having lowest vapour pressure at 25^(@)C is

The vapour pressure of a solution having solid as solute and liquid as solvent is:

The gaseous form of a liquid which occurs below the boiling point of a liquid is called

The vapour pressures of pure liquids A and B are 400 and 600 mmHg , respectively at 298K . On mixing the two liquids, the sum of their initial volumes is equal to the volume of the final mixture. The mole fraction of liquid B is 0.5 in the mixture. The vapour pressure of the final solution, the mole fractions of components A and B in vapour phase, respectively are:

The vapour pressures of pure liquids A and B are 400 and 600 mm Hg respectively at 298 K. On mixing the two liquids, the sum of their initial volumes is equal to the volume of the final mixture. The mole fraction of liquid B is 0.5 in the mixture. The vapour pressure of the final solution, the mole fractions of components A and B in vapour phase, respectively are :
