The incorrect statement is :
Vapour pressure of a liquid always increases by increasing the temperature.
Vapour pressure only depends on temperature and not on the nature of the substance.
Vapour pressure does not depend on the quality of the liquid taken and the surface area of the liquid.
Vapour pressure is not a colligative property and is independent of the concentration of a liquid.
Vapour Pressure -
It is defined as pressure exerted by vapours on liquid surface at equilibrium and condensation.
Factors affecting vapour pressure -
- wherein
It depends only on temperature and nature of liquid.
Vapour pressure also depends on the nature of substance.
