Question

The temperature at which a liquid gets converted into its vapour state is called its-

• A. melting point
• B. boiling point
• C. dew point
• D. freezing point

Answer 1

The correct option is B

boiling point

1. Boiling point is the temperature at which the pressure exerted by the vapour becomes equal to atmospheric pressure.
2. The heat supplied to the liquid after reaching the boiling point is entirely used to change from the liquid state to vapour state.
3. So. the temperature at which a liquid gets converted into its vapour state is called its boiling point.

Hence, option (B) is the correct answer.
