Convection is the heat transfer due to bulk movement of molecules within fluids such as gases ..... Although forced convection from thermal gas expansion in zero-g does not fuel a fire as well as natural convection in a gravity field, some types of ...
Heat energy can be transferred by conduction, convection, and radiation. ... gases move faster when they are heated than they do when they are cold. ... Unlike conduction and convection, radiation can even work through the vacuum of space.
