Consider two identical homogeneous balls, A and B, with the same initial temperatures. One of them is at rest on a horizontal plane, while the second one hangs on a thread (Fig). The same quantities of heat have been supplied to both balls.The final temperatures of which ball is more? (All kinds of heat losses are negligible.
Hint: The dimensions of the balls may change while heating.
