Colored Fabrics and Heat

1
Colored Fabrics and Heat

• 9-3 Project 2

2
Purpose

• To see if the color of a fabric has an effect on
  how much heat it will absorb.

3
Hypothesis

• My hypothesis is that a black fabric will absorb
  more heat because dark material absorbs more heat
  than lighter material.

4
Material

• Parabolic heater
• Different colored fabrics
• Thermometer (fish)
• Pencil
• Scissors
• Sewing needle and thread

5
Method

1. I took the 5 fabrics and cut them into pouches.
2. I put a heater on at 800w (dont know what temp.
   that is).
3. I dropped the thermometer in each fabrics pouch.
4. I hung the pouches about 3 feet away from the
   heater.
5. I then jotted down the temperature of each fabric
   in 5 minutes (doing this process 3 times).

6
Variables

• Manipulated-Fabric used,Heaters
  temperature,Distance and thermometer used.
• Controlled-Heaters temperature,color of
  fabric,Distance from fabric to heater
• Responding-Temperature of fabric,Reading of
  thermometer

Conclusion

• My hypothesis proved correct, the black absorbs
  more heat at a temp. of 35.6 degrees Celsius in 5
  minutes

12
Sources of error

• I may have left the fabric there for a few more
  seconds on one fabric than the other ones
• I may have had the height of one fabric different
  from the other
• The starting temperature may have been higher or
  lower on some fabrics than the others

13
Ways to Improve

• I could have used a different thermometer then a
  fish thermometer
• I could have used a better way to transfer the
  heat into the fabrics
