PROJECT 3 "EXPERIMENT: DENSITY"

DENSITY

INTRODUCTION:

The purpose of this experiment is to determine the density of water, oil and alcohol.

MATERIALS:

- Scales      - Oil       - 3 glasses     - Alcohol      - Water        - Test tube

STEPS:

1.- At first to weight the liquids.

2.- Then to weight the glass.

3.- Next to measure 100 ml of water in the glass and to determine the mass to subtract the value of glass ( to repeat the step with th eoil and alcohol).

4.- Finally to calculate the density of water, oil and alcohol. 

RESULTS:

SUBSTANCES         MASS         VOLUME            DENSITY

Water                          18.3 g             20 ml                0.91 g/ml

Oil                                12.2 g             20 ml                0.61 g/ml

Alcohol                        19.9 g             20 ml                0.64 g/ml

DISCUSSION:

We found that our hypothesis was correct as we predicted because the water is more dense.
