What happens to the mass? What happens to the density? 3- State Archimedes' principle. 4-A balloon is weighted so that it is barely able to float in water. If it is pushed beneath the surface, does it rise back to the surface, stay at the depth to which it is push sink? Explain. (Hint: Does the balloon's density change?) 5-Compared to an empty ship, would a ship loaded with a cargo of Styrofoam sink deeper into the water or rise in the water? Defend your answer.

Explanation / Answer

1.

Helium gas and oil

2.

The Volume of the bread reduces.

The mass of the bread remain same since the quantity of bread has not changed.

density is given as

density = mass/Volume

Since Volume decreases with mass constant , hence the density increases

3.

Archimedies principle : according to this principle , the buoyant force acts on an object which is fully or partially inside the fluid in upward direction and is equal to the weight of fluid displaced by the Volume of the object.
