Question

At what speed does the transfer of heat from the sun to the surface of the earth take place?
​

Answer 1

Hi Buddy,

Speed Of Heat Transfer:

• Heat is transmitted through conduction, convection or radiation. The heat that reaches us from the sun is radiation, which travels at the speed of light. So it would take about 8 minutes .
• The sun's surface emits about 63 million watts of energy per square meter. By the time the energy reaches the Earth, after traveling 150 million kilometers, or 93 million miles, it has diminished to 1,370 watts per square meter at the top of the atmosphere directly facing the sun

Hope it helps you
