through radiation
Convection currents. This means that the soup that is heated moves away from the heat, and the cool soup flows over heat so that warms up
A cold spoon will extract heat from the soup, a spoon that is warmer than the soup will transfer heat to it.
Endothermic, the soup is taking in heat to boil.
Soup
No. It is a noun: "You've still got your soup on the heat."And a verb: "You still need to heat up your soup."But not an adverb; that modifies a verb, and adjective, or another adverb.
Heat always travels from areas of higher temperature to areas of lower temperature. the surface and sides of a container of soup are generally at a lower temperature than the interior of the soup. Of course you may still get some additional heat transfer via convection if the surface is cooler than the soup deeper in the container.
A commercial soup kettle will only keep product warm once hot as you would be waiting a whole day for it to heat product from cold and it would still only be lukewarm
heat the soup on the on the stove to 165 degrees
Transferring heat from the soup to your breath. If you have a pot of hot water and then moc it with cold water, the two will heat exchange until the temperature through out the water is the same. It's the same principle.

You stir it from time to time as you make it.
