The following are the steps involved when you burn your foot on the hot sand at the beach.
Step 1: The sun heats the sand.
Step 2: Heat from the sand is transferred to your foot when you step on it.

Is step 1 an example of conduction, convection, or radiation?

Is step 2 an example of conduction, convection, or radiation?

Answer 1

Answer: step 1 is radiation step 2 is conduction

Explanation: step 1 is radiation because the sun is giving off heat radiation which is heating up the sand without the sun actually touching it

step 2 is conduction because your foot is actually touching the sand and the sand it hotter than your foot, so the sand transfers its heat to your foot until your foot is as hot as the sand
