Written by Brian P Pettegrew Patrick S Market Raymond A Wolf Ronald L Holle and Nicholas WS Demetriades Presentation by Marcello Andiloro Introduction and Background On the evening of 11 Feb 2003 a line a severe thunderstorms moved through southeast Iowa and northwest and central Illinois with winds in excess of 50 . By Ross . Nuechterlein. Convection. Convection.  is the movement of molecules within fluids and is one of the major modes of heat and mass transfer in liquids and gas.. Buoyancy . Buoyancy.  is an upward acting force exerted by a fluid , that opposes an object's weight.. Tanya L. Otte. 1. , Martin J. Otte. 1. , Jared H. Bowden. 2. , . and Christopher G. Nolte. 1. 1.

Heat is always a transfer of energy from objects at a higher temperature to a lower temperature. There are 3 different ways this transfer of energy can happen. Megan . DeCesar (UWM).
