what is thermal equilibrim, and what is thermal energy? what are fluid molecules? does convectin involve the movement of matter in a circular manner only?

thermal equilibrium: no net flow of heat in or out.
thermal energy: The sum of all the interanal stored energy in the kinetic motion of molecules and atoms.
fluid molecules: molecules that can move.
thermal convection: The movement of thermal energy in a closed path.

fluid molecules does not include solid molecules right? what is a closed path?

revised the thermal convection, convection can be an open path also...as the cooling in ones automobile radiator by wind blowing thru it.

thermal convection: the transfer of thermal energy by moving matter across a thermal source.
