# Density of irregular object

Extracts from this document...

Introduction

Density of an Irregular Object

Aim: To find the density of an irregular object.

Apparatus: Measuring cylinder, irregular object (rock), and balance.

Method: 1. Place measuring cylinder on flat working surface.

2. Place 40ml of water into the cylinder.

3. Lower the rock into the water.

4. Observe and record observations.

5.

Middle

Volume of rock –(final volume of water- initial volume of water 15.2ml)

Mass of rock – 61.9g

Data Analysis: Density = Mass / Volume

= 61.9/15.2

= 4.

Conclusion

3 and so the rock is

denser than water. This is likely because as a solid, it’s particles are more closely packed than that in water which is a liquid, which means it’s particles are bonded less strongly and do not vibrate it fixed position but slide over each other and are not tightly packed
