Question

Assertion (A) If we add impurity into a matter, then compressibility of the mixture may change.

Reason (R) Increase and decrease in compressibility depends upon the type of impurity. (NCERT Pg. 173)

Answer 1

Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).

Answer 2

Impurities alter intermolecular forces and structure, affecting compressibility. The specific change (increase/decrease) depends on the impurity type. Thus, both statements are true, and the reason explains the assertion.
