A and B are made up of an isotropic medium. Both A and B are of equal volume. Body B has cavity as shown in Fig.(2). Which of the following statements is true?
A
Expansion in volume of A >expansion in B
B
Expansion in volume of B >expansion in A
C
Expansion in A = expansion in B
D
None of these
Answer
Expansion in A = expansion in B
Explanation
Solution
Thermal expansion in isotropic bodies is independent of shape size & availability of cavity.
