The densities of liquids may be measured using hydrometers. The
hydrometer in the Figure below consists of a weighted bulb with a thin stem , and is floating to the depth shown when it is immersed in a liquid whose density is 0.8g/cm3.

The hydrometer has a mass of 165g and the stem has a uniform cross-sectional area of 0.75 cm2. Calculate;
I. the change in the submerged volume of the hydrometer when it is first placed in a liquid of density 1.00 g/cm3 and then in the liquid of density 1.25 g/cm3.
II. the distance on the stem between the 1.0 g/cm3 and 1.25 g/cm3 graduations.
