Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: The isothermal curves intersect each other at a certain point. Reason: The isothermal changes takes place rapidly, so the isothermal curves have very little slope.A) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B) If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.
C) If Assertion is true but Reason is false.
D) If both Assertion and Reason are false.
Correct Answer: D
Solution :
To carry out isothermal process, a perfect gas is compressed or allowed to expand very slowly. Isothermal curves never intersect each other as they have very little slope.
