A sphere of density p specific heat capacity c and radius r

Last updated: 5/30/2023

A sphere of density p specific heat capacity c and radius r is hung by a thermally insulated thread in an enclosure which is kept constant at a lower temperature than the sphere The temperature of the sphere starts to drop at a rate which depends upon the temperature difference between the sphere and the enclosure and the nature of the surface of the sphere and is proportional to C 3 rp C 3r pc A B D 1 3 r pc 1 rpc
