Questions
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
detailed solution
Correct option is B
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 silverSimilar Questions
The coefficient of expansion of a crystal in one direction (x-axis) is 2.0x 10-6 K-1 and that in the other two perpendicular (y-and z-axes) direction is 1.6 x 10-6 K-1 What is the coefficient of cubical expansion of the crystal?
