Density is the characteristic property of the material and it does not depend on the liquid in which it is immersed
The density of saline water is greater than the density of pure water.
Iron.
Iron has the greatest density, followed by granite, water, and then dry air. Density is the mass per unit volume of a substance, and iron has a higher mass per unit volume compared to granite, water, and dry air.
A block of iron will float in mercury due to the higher density of iron compared to mercury. In water, the iron block will sink because the density of iron is higher than that of water. The buoyant force acting on the iron block is determined by the density of the surrounding fluid.
The structure of an iron ship is such that its density is less than that of water. Anything with a density less than water will float in water.
This depends on the density of the saline water and the density of the tar. For an assumed tar density of 1,15 g/cm3 and for a salt water with a concentration under 200 g/L the answer is yes.
No, even if the density of the iron is less than water, the density of the iron box as a whole would still be greater than water, making it sink. Density is determined by the total mass of an object divided by its total volume, not just the material it is made of.
The density of iron is higher than that of water, so the iron nail sinks in water due to gravity pulling it downwards. The weight of the iron nail is greater than the buoyant force acting on it from the water, causing it to sink.
No, a piece of iron will sink in water because its density is greater than that of water.
Iron sinks in water because it is denser than water. The density of iron is about 7.87 g/cm^3, while the density of water is 1 g/cm^3. This difference in density causes iron to sink when placed in water.
Assuming saline is 0.9% sodium chloride in water, the density is approximately 1.0046 g/ml. Therefore, 10 ml of saline would weigh around 10.046 grams.
Solid iron will float in liquid Mercury. In most liquids it will sink.
