• The buoyant force on an object depends on the volume of the object that is underwater.
• The buoyant force on an object increases as it is lowered into water because more volume of the object is displaced by water, which increases the buoyant force.
• The buoyant force on an object is equal to the weight of the water it displaces.
• When the buoyant force on an object is equal to the weight of the water it displaces, the object will float and remain suspended in the water without sinking or rising.

5A. The volume of the rectangular object is 10 x 5 x 20 = 1000 cubic centimeters.

5B. The density of the object is 800 grams / 1000 cubic centimeters = 0.8 g/cm3.

5C. The object will sink in water because its density is greater than the density of water, which is 1 g/cm3.

• Iron will sink in mercury because its density is less than the density of mercury, which is 13.5 g/cm3.
• It is incorrect to say that heavy objects sink in water because an object's density, not its weight, determines whether it will sink or float in water.
• Steel ships float because their shape allows them to displace a volume of water that is greater than their own weight, which creates a buoyant force that supports the weight of the ship and keeps it afloat.
• The rock will sink in mercury because its density is less than the density of mercury, which means that it is more dense than the liquid it is placed in.

What is buoyancy and density?

Buoyancy is the upward force exerted on an object immersed in a fluid (liquid or gas), which opposes the object's weight. This force is caused by the difference in pressure between the top and bottom of the object.

Density is a measure of how much mass is contained in a given volume of a substance. It is typically expressed in units of kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). The density of an object can determine whether it floats or sinks in a fluid, with objects that are less dense than the fluid rising to the surface and those that are more dense sinking to the bottom.
