Question

Specific gravity usually means relative density with respect to ice. Is the statement True or False?

Answer 1

Hint
The specific gravity is the magnitude relation between the density of an associate degree object and a reference substance. The particular gravity will tell us, supporting its price, if the thing can sink or float in our reference substance. Typically, our reference substance is water that forever encompasses a density of one gram per millimeter or one gram per cubic centimeter.

Complete step by step answer
When we leave within the summer to get pleasure from the pools, and also the rivers, we tend to continuously get to make certain that every one of our instrumentation and safety measures is operating and in place. One of these factors is what we do tend to call the specific gravity.
An object's density may be a life of how compact or significant it's, in a very given volume. we tend to measure density in mass per unit volume that is written using measures like grams per milliliter$\left( {g/mL} \right)$, grams per centimeter cube $\left( {g/c{m^3}} \right)$, or kilograms per liter $\left( {kg/l} \right)$.
Here are two objects with totally different densities. On the left is an object extremely packed with particles. which means it's a high density. On the right is an object with an occasional density. we'll see that the particles aren't packed tightly however that fewer particles are occupying constant volume. to seek out the density of an object, we tend to divide its mass by its volume. For example, take an object with a volume of $4{\text{ litres}}$ and a mass of $1{\text{ kg}}$. we tend to plug these numbers into the density formula and find out that its density is $0.25{\text{ kg/l}}$.
As we know, Specific gravity is the density of a substance concerning water.
$Specific{\text{ gravity}} = \dfrac{{{\text{Density of an Object}}}}{{Density{\text{ of Water}}}}$
Specific gravity is denoted by $\rho $. It has no unit.
We can say that Specific gravity is the density of an object concerning the density of water. Hence the statement is incorrect which leads to a false statement.

Note
The main use of Specific gravity is- When we have to differentiate between two similar metals then we use this. For example, It is mostly used by a person who buys or sells gold.
Another use is for estimating the weight of the material. It is a dimensionless quantity. In pharmacy, their concepts are widely used.
