Introduction
In this experiment (Effect of Color on the Characteristics of a Heat Barrier Material), we will be determining the effect of colour on heat barrier elements. Whatever result we will obtain in this experiment would help us in identifying the effect of colour on heat barrier elements for protecting fire on heated wooden structures and utility poles.
We hypothesised that the black colour would absorb the most heat, while the white colour reflects the most heat.
Aim
To determine the effect of colour on heat barrier elements.
Theory
1. The term that is used for denoting the prevention from the transfer of heat is termed heat barrier.
2. Insulation is used in the context of heat barriers.
Requirements
1. Five wooden boards,
2. White, black, green, brown, and red colour board.
3. Ten supports,
4. Temperature probe,
5. 500-watt heat lamp,
6. Thermometer,
7. Gas torch,
8. Notebook.
Procedure
Step 1: Take five wooden boards, all with the same dimension.
Step 2: Drill a hole in the centre of each of the holes.
Step 3: Coat the top of each board with black, green, brown, white, and red colours respectively.
Step 4: Take ten supports, coating up and hole down, and place each board on two supports.
Step 5: Insert a temperature probe into the hole of each of the five boards.
Step 6: Take a 500-watt heat lamp and place it above the board.
Step 7: Record the temperature of the board every second for thirty minutes.
Step 8: Now, turn off the lamp.
Step 9: Record the temperature of the board every second for sixty minutes.
Step 10:. Further, replace the lamp with a gas torch.
Step 11: Repeat the same experiment with the gas torch.
Step 12: Record your observations.
Observation
1. We compared the heating and cooling of the board using a curve fit parameter.
2. This curve (heating and cooling) showed the consistency of all five colours white, red, black, green, and brown.
3. We observed that the white colour board reflected most of the heat. On the other hand, the black colour board absorbed most of the light.
Result
1. Our hypothesis is correct. In that, we assume that black will absorb most heat and white colour will absorb less heat.
2. From our experiment, we have seen using the curve that the white colour board reflected most heat and absorbed almost no heat. On the other hand, the black colour board absorbed most heat and reflected almost none.
3. Using the result, we can explain the temperature increase on the surface of a fire protecting coat with time.
Precaution
1. Temperature should be recorded for up to thirty minutes for heating and sixty minutes for cooling of the board.
2. Record your observation precisely.
Conclusion
In this experiment, we determined the effect of colour on the heat barrier element.
