# Find the Density of the body

• vbalaji555
In summary, density is the measure of how tightly packed the particles of a substance are, calculated by dividing its mass by its volume. To find the density of a body, a scale, ruler, and possibly a container are needed. It is important to know the density of a body as it can provide information about its composition and properties, and also plays a role in various scientific fields. The density of a body also affects its buoyancy, with higher density causing sinking and lower density causing floating.

A Body Weight 7.55kg in air 5.17kg in water and 6.35kg in a certain liquid. Find the Density of the body and that of the liquid if Density of water is 1000 kg/m^3

## The Attempt at a Solution

Weights aren't measured in kilograms. Are those values you gave supposed to be the weights, measured in Newtons, or, are the masses, measured in kilograms?

Show attempt to solution.

## 1. What is the definition of density?

Density is defined as the amount of mass per unit of volume of a substance. In other words, it is a measure of how tightly packed the particles of a substance are.

## 2. How do you find the density of a body?

The density of a body can be calculated by dividing its mass by its volume. The equation for density is D=m/v, where D is density, m is mass, and v is volume. The resulting unit for density is typically grams per cubic centimeter (g/cm3) for solids and liquids, and grams per liter (g/L) for gases.

## 3. What tools are needed to find the density of a body?

To find the density of a body, you will need a scale to measure its mass and a ruler to measure its dimensions and calculate its volume. You may also need a graduated cylinder or other container to measure the volume of irregularly shaped objects.

## 4. Why is it important to know the density of a body?

Knowing the density of a body can provide valuable information about its composition and properties. It can help identify substances and distinguish between different materials. Density also plays a crucial role in various scientific fields, such as chemistry, physics, and engineering.

## 5. How does the density of a body affect its buoyancy?

The density of a body determines its buoyancy, or its ability to float or sink in a liquid. A body with a higher density than the liquid it is placed in will sink, while a body with a lower density will float. This is due to the principle of buoyancy, which states that an object will float if it displaces an amount of liquid equal to its own weight.
