I must solve this problem, please help me, which equations i should use?
Most of us have passed our finger through a 800C candle flame and know that if we limit exposure to about 0.25 s, we will not be burned. Why not? Show all the calculations that support your answer. The burn treshold of human skin is about 65C. Assume human flesh has properties similar to beef and h=100 W/m^2.K.
