Question

Based on the statements given here choose the correct answer.
(1) Boiling point of a liquid increases with increase in temperature.
(2) The volume of liquids increases on boiling and the vaporisation curve shows the variation of the boiling point of a liquid with pressure and expands the equilibrium state between liquid and vapour phase.

• A. (1) and (2) are true and (2) explains (1)
• B. (1) and (2) are true but (2) does not explain (1)
• C. Only (1) is true
• D. Only (2) is true

Answer 1

The correct option is A

(1) and (2) are true and (2) explains (1)

(1) Boiling point of a liquid increases with increase in temperature.

(2) The volume of liquids increases on boiling and the vaporisation curve shows the variation of the boiling point of a liquid with pressure and expands the equilibrium state between liquid and vapour phase.

Both the statements are correct and second is the explanation of first.
