Exploring Evaporation through Colors

by | Aug 31, 2022 | Physics, Experiments

Introduction

In this experiment(Exploring Evaporation through Colors), we will be determining the kind of colour that helps in evaporating water more efficiently.

We hypothesised that the red plastic would work efficiently in evaporating water.

Aim

To find what colour of plastic among red, black, purple and clear help in evaporating water more efficiently.

Theory

The plastic used in food containers is very thin and has less density. Its molecule does not hold much heat. When the water evaporates from the container, its drops quickly cool down the plastic, which lowers the rate of evaporation.

Requirements

1. Four plastic containers

2. Sixteen cups of water

2. One small cup

4. Six tablespoons of dirt

5. Tape

6. One sheet of coloured plastic

7. One quarter for weight

8. Notebook

Procedure

Step 1: Take four plastic containers.

Step 2: Put sixteen cups of water and six tablespoons of dirt inside each container.

Step 3: Cover each container with one sheet of coloured plastic.

Step 4: Use one quarter as weight on each of the containers.

Step 5: Record your observations.

Observation

We observed that the clear plastic worked more efficiently.

Result

Our hypothesis is wrong; in which we assumed that the red plastic would work efficiently because of being translucent and dark shade, but our observation showed that the clear plastics worked more efficiently.

Precaution

1. Record the observation precisely.

2. Take help in building containers.

Conclusion

In this experiment, we have discovered a plastic colour that can be used effectively for evaporating water.
