Coefficient of apparent expansions of a liquid in gold vessel is ‘G’ & when heated in a silver vessel is ‘S’ if coefficient of linear expansion of Gold is ‘A’, coefficient of linear expansion of silver is

coefficient of real expansion of liquid is same in gold and silver container γRgold=γRsilver γa+3αggold=γa+3αgsilver;here γa=coefficient of apparent expansion of liquid;αg is coefficient of linear expansion of container substitute the given values G+3A=S+3α G+3A−S=3α α=G−S+3A3=coefficient of linear expansion of silver
