An Al ball has a radius of 5cm. The true weight is 0.75kg. 1.Find the increase in volume when the temperature increases by 30'C. 2.The Al ball is fully submerged in a liquid at 30'C. The apparent weight is 0.373kg. Now the metal ball is fully submerged at a temperature 60'C. Now the apparent weight is 0.385kg. Find the real volume expansively of the liquid. Linear expansivity of Al= 2.6*10^-5
