Question

Assertion: Standard boiling point of a liquid is slightly higher than the normal boiling point
Reason: $1$ bar pressure is slightly less than $1atm$ pressure

• A. Assertion and reasoning are correct statements and reason is the correct explanation for assertion
• B. Assertion and reasoning are correct statements and reason is not the explanation for assertion
• C. Assertion is correct, reason is wrong
• D. Assertion is wrong, reason is correct

Answer 1

Answer: (D)

Assertion it is incorrect because standard boiling point (b.p. at $1$ bar pressure) of a liquid is slightly lower than the normal boiling point (b.p. at $1atm$ pressure). It is because 1 bar pressure is slightly lower than $1atm$ pressure.
Reason It is correct because
$1atm=1.01325bar$.
Since, Assertion is incorrect, Reason is correct.
