Question

An aluminum cup is filled to the brim with precisely 0.400 liters of mercury at a temperature of 20 °C. The cup and mercury are then allowed to warm up to a temperature of 50 °C
Calculate the change in volume of the cup and the change in volume of the mercury?
How much mercury over flows the cup?

Answer 1

Acquaint yourself with the coefficient of thermal expansion. For solids, the linear expansion coefficient is usually tabulated. For liquids, it is usually the volume expansion coefficient that you will find in tables.

Subtract the volume expansion of the aluminum from that of the mercury, to get the overflow.
