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

[BobbySells32]

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

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
