Convection and... DUMPLINGS!!!!

Convection is the transfer of heat through air or liquid currents, or like steam or fog around DUMPLINGS!!!  Steam in a steamer will cook the DUMPLINGS!!!!  Also, air and water heating systems are based on the concept of convection but more specifically convection currents. These currents are created by the simple fact that hot molecules are less dense so the hot air or water will rise from your furnace and then come back down when it cools.  This is why you need a heating system to cook DUMPLINGS!!!!!!!
