The specific gravity of an object is numerically the same as its density as measured in the metric system. true false

The  correct answer is 'True'.

Specific gravity is the ratio of the density of a substance to the density of water. It has no unit.

Density of a substance is the ratio of its mass to its volume with unit as g/ml.

The density of water is 1 g/ml. Therefore,  the specific gravity of an object is numerically the same as its density.

It's true

Explanation:

Density is defined as the division between the mass of an object and the volume occupied by that object. Its unit of measure in the International System is the kilogram per cubic meter (kg/m^3). Meanwhile, specific gravity is defined as the weight of an object divided over the weight of water at 4°C. The specific gravity is dimensionless and coincides numerically with the density.

mg3n2 is known as magnesium nitride

i don't think ke is an compound

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
