MEASURING MATERIAL PROPERTIES

INTRODUCTION

The density of a substance is defined as its mass divided by its volume. Since density is the result of the mass of a substance and how much space it occupies, it is a fundamental or characteristic property of a substance.

I intend to carry out an experiment in the laboratory of finding and comparing the density of various materials.

AIM

1. to measure dimensions and calculate volumes
2. to mesure mass
3. to calculate densities of common materials
4. to tabulate results and present results as a bar chart

APPARATUS

• materials
• senior callipers

METHOD

1. first the steel cylinder was chosen as the first ,material to investigate , the dimension  (height ,length , diameter and radius) were observed by using the
2. Then the material was placed on the weighing machine and weighed, the mass was recorded.
3. the volume was then calculated by the dimensions discovered

1. then the density was calculated by using the formulae  -  density = mass

Volume

1. all the results were recorded in the table
2. Steps 1-5 were then undertaken for each of the other 7 materials left to investigate.
3. After all the materials were examined, a graph was then produced of the density of the individual materials.

RESULTS

CALCULATIONS

1. STEEL CYLINDER

VOLUME = 4.1 X 2.2 X π  = 62.34     DENSITY = ...
