Here is the problem which I am struggling on, please help me!
Problem: Radiant heat makes it impossible to stand close to a hot lava flow. Calculate the rate of heat transfer by radiation from 1.00 m2 of 1300ºC fresh lava into 32.0ºC surroundings, assuming lava's emissivity is 1.0.
Please provide equations and steps used in account set-up and solution.
