Catching Rays

by | Oct 24, 2022 | Physics, Experiments

Introduction

In this experiment(catching rays), we will be determining which material is the optimum heat collector among rubber, aluminium, and copper. We choose to perform this experiment using renewable sources of energy such as solar and wind energy despite non-renewable sources of energy such as coal, gas, and oil reserves.

Aim

To determine which material proved to be the optimum heat collector among rubber, copper, and Aluminium.

Theory

1. Our hypothesis is that Copper is the most efficient source of heat collector.

2. The device which is being designed to collect heat by absorbing sunlight is termed a solar thermal collector.

Material required

1. Copper,

2. Aluminium,

3. Rubber,

4. A shallow box with a removable transparent lid,

5. Styrofoam,

6. Sensitive thermometer,

7. Notebook.

Procedure

Step 1:Use three building materials (copper, aluminium, rubber) as the variable of this experiment.

Step 2: Build a collector, which is a shallow box with a removable transparent lid.

Step 3: Using styrofoam, insulate the collector.

Step 4: Use a sensitive thermometer for recording the inside temperature of the collector and the ambient air.

Step 5: Research the conduction level of each material.

Step 6: Every five minutes until thirty minutes, measure the temperature inside the collector, with each material, three times.

Step 7: After measuring all the three variables, one cycle is completed.

Step 8: Repeat this cycle four times and note the temperature and weather each time.

Step 9: Compare the obtained result with our hypothesis.

Observation

1. This experiment had partly supported our hypothesis.

2. Copper did not attain the highest temperature but proved our hypothesis to be the best source of heat collector.

3. For improving the result, we could use a more accurate thermometer that has a larger range.

Result

1. Aluminium had a high temperature but copper was a better conductor.

2. Copper did not get affected because of temperature and weather.

3. On the other hand, aluminium was unpredictable as it depended on the temperature and weather.

4. Rubber collected heat and kept it for a longer period.

Precaution

1. For better results use three different collectors.

2. Use a thermometer with a larger range.

3. Record your observation carefully.

Conclusion

In this experiment, we have determined which material among copper, rubber, and aluminium will prove to be a better collector of heat.
