Question

Which object will sink in freshwater, which has a density of 1.0 g/cm3?

Object 1, which has a density of .08 g/cm3
Object 2, which has a density of 1.9 g/cm3
Object 3, which has a density of .06 g/cm3
Object 4, which has a density of .03 g/cm3

Answer 1

Explanation:

all object having a mass volumic >1 kg/dm^3 will sink in water which has a mass volumic of 1kg/dm^3 .

Answer 2

Answer:

Object 2, which has density of 1.9.

Explanation:

Density: It is the measure of compactness among the atoms of a substance. A denser substance would have more compact atoms than a substance with less density. It is the ratio of mass and volume.

The density of freshwater is 1.0 g/cm3 or 1000kg/m3. Whenever an object with density higher than that of water is placed on the water surface , it will sink while a substance with density less than 1.0g/cm3 when placed on the water surface will float. Among given options, only object 2 has density more than that of water, so it will sink in freshwater.
