Stephan-Boltzmann Law Help for Science Fair Project - Needed Now!

Click For Summary
SUMMARY

The discussion centers on applying the Stefan-Boltzmann Law to calculate energy flow and energy carried by visible and infrared photons for a science fair project. The user is specifically working with temperature data for colored construction paper squares and seeks guidance on using the formula P=σAT^4, where σ is the Stefan-Boltzmann constant (5.67x10^-8 J/sm²K⁴). The temperatures provided in Celsius and Kelvin for different colors are essential for the calculations. The user expresses confusion about how to begin the calculations.

PREREQUISITES
  • Understanding of the Stefan-Boltzmann Law
  • Basic knowledge of thermodynamics
  • Familiarity with temperature conversion between Celsius and Kelvin
  • Ability to perform calculations involving exponents
NEXT STEPS
  • Research the application of the Stefan-Boltzmann Law in practical scenarios
  • Learn how to convert temperature from Celsius to Kelvin accurately
  • Explore examples of energy flow calculations using P=σAT^4
  • Investigate the significance of visible and infrared photon energy in thermal radiation
USEFUL FOR

Students working on science fair projects, educators teaching thermodynamics, and anyone interested in the practical applications of the Stefan-Boltzmann Law in physics.

Hello, I am in DIRE need of help with my science fair project and am completely stuck. All/most relevant information should be able to be found here: http://sciencebuddies.org/science-f...OjEsaWE6UGh5cyxwOjUscmlkOjEyNDE1MzMw&from=TSW

1. I am stuck on number 7, "Now that you have the data, calculate the energy flow and the energy carried by the visible and infrared photons." The squares of construction paper were 4*4 inches. Data for the temperature is as follows (Celsius; Kelvin)
Red: 38.4; 311.4
Blue: 40.4; 313.4
Yellow: 37.4; 310.4
White: 36.6; 309.6
Black:45.1; 318.1
2. Its something to do with the Stephan-Boltzmann Law but I'm not entirely sure
3. I have no clue where to even BEGIN on a solution
 
Physics news on Phys.org
Anyone? :(
 
I think you need to use P=σAT4, it gives you the energy flow from a surface with temperature T.
σ is Stefan–Boltzmann constant and is equal to 5.67x10-8 J/sm2K4
