You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.

Surface refers to the outermost part of an object or material, the area that is exposed. Density, on the other hand, is a measure of how much mass is contained in a given volume of a substance. Essentially, surface is related to the external appearance or boundary of an object, while density describes how closely packed the particles are within that object.

What seismic wave refracts and cannot penetrate the core?

Surface waves such as Love waves and Rayleigh waves refract when they encounter the core beneath the Earth's surface. These waves cannot penetrate the core due to the difference in density and composition between the core and the surrounding layers of the Earth.


Which is caused by density difference?

Buoyancy is primarily caused by density differences. When an object is immersed in a fluid, the upward force it experiences, known as buoyant force, is a result of the density difference between the object and the fluid. Objects with a lower density than the surrounding fluid will float, while those with a higher density will sink.


What is the difference between bulk density and density?

Density refers to the mass of a substance per unit volume, while bulk density is the mass of a mixture or material divided by its total volume including voids. Bulk density takes into account the space between particles and is often used in industries such as agriculture and mining to estimate the amount of material that can be stored or transported.


Why Does rubber float in oil?

Rubber has a lower density compared to oil, which causes it to float on the surface of the oil. This difference in density results in a buoyant force that pushes the rubber to float rather than sink.


What is the difference between floating and sinking objects and the density of the liquid they are in?

Floating objects have a lower density than the liquid they are in, causing them to float. Sinking objects have a higher density than the liquid, causing them to sink. The density of the liquid determines whether an object will float or sink based on the relationship between the object's density and the liquid's density.

What is the relationship between density and surface tension?

as we know the relation between surface tension and temperature is inverse, and that of temperature and density also has inverse proportion, then it is clear that the '''surface tension is directly proportion to the density'''.

What fraction of an iceberg lies hidden below the surface of the water?

Approximately 90% of an iceberg lies hidden below the surface of the water. This is due to the difference in density between ice and water, causing the iceberg to float with a significant portion submerged.

Does density of water increase or decrease the surface tension of water?

The surface tension of water is due to cohesive forces between water molecules. Density does not directly affect surface tension, but impurities or additives can alter it. Essentially, the surface tension of water remains constant regardless of its density.
