Chapter 0, Problem 0.18CP

Which block in each of the following drawings of a balance is more dense, red or green? Explain.

Interpretation Introduction

Interpretation:

The denser block in drawing of a balance has to be identified and explained.

Concept Introduction:

Density:

Density can be defined as property that links mass of an object to its volume. It derived quantity and its unit is $\text{g}{\text{ml}}^{\text{-1}}$ for liquids and $\text{g}{\text{cm}}^{\text{-3}}$ for solid. The density of material can be calculated with the help of formula,

$\text{Density=}\frac{\text{Mass}\left(\text{g}\right)}{\text{Volume}\left(\text{ml}\text{or}{\text{cm}}^{\text{3}}\right)}$

Explanation of Solution

It is known that,

Density is directly proportional to mass and inversely proportional to volume.

In (a), red is identified as denser block because it is found have more mass and less volume than green block.
