If a solid ball of metal has a concentric spherical cavity with in it if the ball is heated the volume of the cavity will
Options
(a) increase
(b) decrease
(c) remains unchanged
(d) None of these
Correct Answer:
increase
Explanation:
When a solid ball has a concentric spherical cavity within it is heated, the volume of the cavity will increase.
