Question

If you hold your hand over a pot of boiling water, it feels hot. Explain how the boiling water is transforming heat to your hand

Answer 1

I don't no if this helps but the body heat from your hand causes the liquid to boil, which in turn makes the liquid evaporate, turning it to gas. The expanding gas pushes the liquid upwards and when you release your hand, equilibrium is re-established.

Answer 2

Answer:

Conduction

Explanation:

The boiling heat is transforming heat to my hand through conduction. Conduction is a mode of heat transfer which is the transfer of heat from one body to another without any actual movement of the bodies. It does not occur in vacuum.

In conduction, heat is transferred from a region of high temperature to a region of low temperature. This means that the temperature of the pot of boiling water is higher than that of the hand and as such heat will be transferred from the pot to the hand due to temperature gradient. Note that there is no need need for the bodies in question (pot and the hand) to move before the heat will be transferred.
