Detailed Solution

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
