Question

imagine you pour some hot chocolate into a mug. How does the heat spread throughout the hot chocolate?

Answer 1

I'm pretty sure that the answer is convection!

Step-by-step explanation:

Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

Answer 2

When a molecule is heated, it gains energy that allows it to vibrate at a higher speed. When the molecules vibrating quickly bump into other molecules, they pass some of that energy on to the other molecules which in turn causes them to vibrate at a higher speed. The energy is passed on to every molecule in the hot chocolate, causing it to be equally heated.
