Question

Vapour pressure of a liquid increases with :

• A. decrease in temperature
• B. increase in temperature
• C. increase in surface area
• D. increase in volume

Answer 1

Answer: (B)

increase in temperature

Vapour pressure is the pressure exerted by the vapour when vapour is in equilibrium with liquid or solid or both the states of the same substance.

As the temperature of solid or liquid increases, it's vapour pressure also increases.

Therefore, option B is correct.
