Question

Statement: Water vapour causes more burning sensation than boiling water at the same temperature.
Reason: Water vapour has more energy than boiling water due to the latent heat of vaporization.

• A. Both the statement and the reason are true and the reason is the correct explanation.
• B. Both the statement and reason are true but the reason is not the correct explanation.
• C. The statement is true but the reason is false.
• D. The statement is false but the reason is true.

Answer 1

The correct option is A Both the statement and the reason are true and the reason is the correct explanation.

Water vapour has more energy than boiling water, although both are at the same temperature. It is due to the high of latent heat of vaporization in water vapour. Hence more burning sensation is caused by water vapour.
