How soup on a pan on a stove is heated by conduction and convection?

Question

Please explain how soup on a pan on a stove is heated by conduction and convection.... please?

Answer 1

conduction is first, the heating element is touching the pan which touches the soup and heats it up. convection is heat transfer through a gas or liquid, in this case the soup.

Answer 2

Slurp, slurp. The conduction transfers heat from the heating element in the stove through the pan thickness to the inside surface. A highly conductive metal that is sturdy is good for this. The heat then transfers into the liquid, where it heats elements of the liquid that mix more vigorously with other part of the soup. This is the general convection process.

Answer 3

*...The heat of the stove first passes through the metal of the pan by conduction ...collision of the molecules of the metal as their Kinetic Energy increases with temperature.

*...Then, the heat passes into the soup from the bottom and causes the liquid, as it heats up to rise due to expansion and decrease in density (the hotter liquid rises).
*...As the hot liquid rises, the cooler liquid flows round and down to take its place and this process continues.
*...The hot rising and cooler falling liquid, sets up circulating currents within the liquid and you get the 'rolling' action in the pan..I'm sure you've seen it. This is Convection.

Answer 4

The metal of the pan conducts the heat through to the soup and convection currents of heat through the soup finish the job.
