Question

Mate I don't understand can you help me how it happens.

Answer 1

Answer:

on heating a solid its molecules expand due to which the solid also expands

Explanation:

here as the size of the ring is same so the ball couldn't fit into the ring

The answer for the conclusion blanks is

expands , metallic frame

I hope it's clear

thanks

Answer 2

Here, it is seen that on heating, the ring does not pass through. It's only possible when:-

1) The size of ring decreases or;

2) The size of the ball increases.

According to the given experiment, the ball is strongly heated and nothing is done to the ring. The ring that we are using before and after, is one and the same. So, there's nothing that the ring contributes to our observation. Thus, the 1st case is ruled out.

Now, the only possible reason for the ring to not pass through after strongly heating the ball, is that the size of the ball has increased.

Yes, it has. ALMOST all the objects in this universe expand on heating. Here, the expansion is too obvious as we are using a METALLIC ball.

When heat is supplied to the ball, the kinetic energy of the molecules of the metal ball imcreases. Due to this, the molecules start vibrating. It's just like all the molecules are connected in a spring grid. The spring force that pushes the molecules farther out is more than the one that pulls it in. It's not actually the spring force, but analogous to it. Thus, the body expands on heating.
