1.	A piece of metal floats on mercury. The coefficient of volume expansion of the metal and mercury are y, and Y2 respectively. If the temperatures of both mercury and metal are increased by an amount Delta theta,by what fraction does the volume of metal submerged in mercury change ?
Answer» Solution :`(1 + gamma _(2) DELTA theta)/(1 + gamma _(1) Delta theta)`
