Question

1. You are provided with a piece of rock and
common laboratory equipment. How will you
proceed to find its density? Diagrams not
required.​

Answer 1

Explanation:

Density = mass / volume.

mass of the given rock piece is measured using physical balance.

Let us take a measuring jar and fill water in it partially.

By immersing the given rock piece in measuring jar using a piece of thread, we can measure the displaced volume of water.

This displaced volume is the volume of given piece of rock.

By knowing mass and volume, we can calculate its density
