| Apr 14, 2012 at 13:51 | comment | added | Snowhare | Here is a way to think about it that makes the answer obvious. Replace 'cut a hole into with 'draw a circle on' and consider what happens to the drawn circle when the disc is heated. | |
| Apr 14, 2012 at 9:02 | comment | added | user8673 | i have a doubt.Consider the particles on the outer circumference of the disc expand outwards..and the inner circumference expand inwards....so the volume is increasing with the mass remaining constant...so with the explanation in one of the above answers it is possible that the hole's diameter decreases as the density is decreasing(in one of the answers it was mentioned that as density increases it is not possible)..but it does not happen.why? | |
