Some steem balls are fixed at the bottom of a silica bulb of negligible exapnsivity. The bulb holds 340 gm of mercury at 0^(@)C when filled, in the absence of the steel balls and 255 gm of mercyr, when the steel balls are inside. On heating the bulb and its contents (steel balls and mercury) to 100^(@)C, 4.5 gm ofmercury overflows. Find the coefficient of linear expansion of steel. gamma_(Hg)=180xx10^(-6).^(@)C^(-1) |
