If you hold your hand over a pot of boiling water, it feels hot. Explain how the boiling water is transferring heat to your hand. Convection, because boiling water has enough energy to turn into water vapor, which rises through the air and transfers heat to your hand Conduction, because as the water boils, liquid water droplets splash out of the pot and hit your hand, transferring heat Radiation, because heat from the sun warms the top of your hand and that transfers to the water Radiation, because the heat energy moves from the pot to the air and from the air to your hand

Convection, because boiling water has enough energy to turn into water vapour, which rises through the air and transfers heat to your hand.

Explanation:

When water boils, it forms hot water vapour (steam). The hot vapour is less dense than air, so it rises and carries its heat energy along. This process is called convection.

B is wrong. Unless the water is boiling quite vigorously, liquid water droplets do not splash out of the pot.

C is wrong. You may be indoors where the sun is not shining.

D is wrong. Radiant energy would move directly from the pot to your hand.
