Is the measurement of the density of a substance as compared to water.

a. liquid gravity
b. precise gravity
c. ideal gravity
d. specific gravity

Option (D) is the correct answer.

Explanation:

When density of a substance is measured with respect to the density of a standard substance which is usually water then the ratio is known as specific gravity.

Whereas density is defined as the mass of a substance present in per unit volume.

Mathematically,        Density =

For example, specific gravity of water is 1 and a substance that has specific gravity less than specific gravity of water will float otherwise it will sink.

So, specific gravity of mercury is 13.6. Hence, it will sink in water.

Thus, we can conclude that specific gravity is the measurement of the density of a substance as compared to water.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
