1 Why is it important that no air bubbles adhere to the objects during measurements? 2 T he specific gravity of gold is 19.3. What is the mass in grams of a cubic centimeter of gold? What is the weight in pounds of a cubic foot of gold? block of metal having a density of 9.00 gm/cm3 has an apparent weight of 180 gm in water and 135 gm when submerged in a liquid. What is the density of the liquid 4 A block of wood and a block of lead of the same mass are weighed carefully on a trip scale using brass weigh weights of these blocks the same? Explain 5 A submarine floats at rest 50 ft deep in water. Without using the propeller 6 A rock has a specific gravity of 1.30. Gordon can lift 120 pounds. How many cubic feet of this rock can he Water? how can the captain make it surface? Sink? lift in air? il having a density of 0.80 gm/cm3 floats on water of density 1.0 gm/cm3. A solid object which has a specific gravity of 0.90 is dropped into the container. Locate its exact position of restExplanation / Answer

It important that no air bubbles adhere to the objects during measurements because it affects the volume of the sample. Your results will be affected because volume is the factor you are trying to determine. Air bubbles displace water just like anything else.
Air bubbles would make it seem like your sample had a great volume than it really does. A higher volume would result in a lower density.
