Because like any heated food, it starts to cool when removed from the stove.
through radiation
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.
Heat will flow from the bowl of soup, which is at 125 degrees Fahrenheit, to the cooler environment of the refrigerator, which is at 38 degrees Fahrenheit. This transfer of heat occurs because heat naturally moves from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached. As a result, the soup will gradually cool down while the refrigerator's temperature remains largely unaffected.
Heat travels through a metal spoon by conduction, where it is transferred from particle to particle within the spoon as they vibrate due to being heated. The metal spoon acts as a conductor, allowing the heat to flow from the hot soup to the cooler parts of the spoon and eventually warming the handle.
A cold spoon will extract heat from the soup, a spoon that is warmer than the soup will transfer heat to it.
Warm things generally expand and take up more room. If you heat it to boiling, some of the water turns to steam, which expands greatly.
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
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.
The spoon will absorb heat from the hot soup through conduction, causing it to become warmer. This transfer of heat occurs because there is a temperature difference between the hot soup and the spoon, leading to thermal energy flowing from the soup to the spoon until they reach thermal equilibrium.
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
