Avg difficulty 2.5

Radiation makes it impossible to stand close to a hot lava flow. Calculate the rate of heat transfer by radiation from 1.00 m21 . \text{00} \textrm{ }\text{m}^{2} of 1200ºC\text{1200}º \text{C} fresh lava into 30.0ºC\text{30} . 0º \text{C} surroundings, assuming lava’s emissivity is 1.00.
