An iron cube floats in a bowl of liquid mercury at 0 C.

Question

a) If the temperature is raised to 28 C, will the cube float higher or lower in the mercury?
b)By what percent will the fraction of volume submerged change?

Thanks

Answer 1

You need the density of iron, mercury, at each temperature, or have the coefficent of volume expansion and then figure the density at the second temp.
