Physics · JEE | MECHANICAL PROPERTIES OF SOLIDS
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Gases are about a million times more compressible than solids. Reason (R): The bulk modulus of gases is extremely large compared to solids. In the light of the above statements, choose the correct answer from the options given below:
View Answer & Solution
Correct answer · Option A
(A) is true but (R) is false.
Explanation
Compressibility is \( k = 1/B \). Gases have very small bulk moduli compared to solids, hence their compressibility is exceptionally large.
