Icebergs have an average density of 920 kg/m³.Seawater has an average density of 1030 kg/m³.An iceberg floats in seawater.What percentage of the iceberg's volume is in the air above the surface of the seawater? A)10.7% B)12.0% C)47.0% D)50.0%

Question

Quizplus · Accepted Answer

The percentage of an iceberg's volume that is above the surface can be calculated using the principle of buoyancy, which states that the volume of water displaced by the iceberg is equal to the volume of the iceberg submerged. The density of the iceberg (920 kg/m^3) is 89.3% of the density of seawater (1030 kg/m^3), meaning 89.3% of the iceberg's volume is needed to displace enough water to equal its weight. Therefore, 100% - 89.3% = 10.7% of the iceberg's volume is above the surface.
