Radiation makes it impossible to stand close to a hot lava flow. calculate the rate of heat transfer by radiation from 1.00 m^2 of 1250°c fresh lava into 34.0°c surroundings, assuming lava's emissivity is 1.00

3.045 x 10^5 Joule per second

Explanation:

A = 1 m^2

T = 1250 degree C = 1250 + 273 = 1523 K

To = 34 degree C = 34 + 273 = 307 K

e = 1

Stefan's constant, σ = 5.67 x 10^-8 watt per meter squared per kelvin to the fourth

Use of Stefan's Boltzmann law

Energy radiated per unit time

E = σ A e (T^4 - To^4)

E = 5.67 x 10^-8 x 1 x 1 (1523^4 - 307^4)

E = 3.045 x 10^5 Joule per second

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
