Question

what do you mean by specific gravity of a metal? please explain in simple words​

Answer 1

Answer:

Specific gravity, also called relative density, ratio of the density of a substance to that of a standard substance. ... If a substance has specific gravity less than that of a fluid, it will float on that fluid: helium-filled balloons will rise in air, oil will form a slick on water, and lead will float on mercury

Answer 2

ANSWER:-

Definition : The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature.

EXPLANATION IN SIMPLE WORDS:-

Specific gravity, also called relative density, ratio of the density of a substance to that of a standard substance.

For example : If a substance has specific gravity less than that of a fluid, it will float on that fluid: helium-filled balloons will rise in air, oil will form a slick on water, and lead will float on mercury.
