Forget thermo dee; I see the problem...

More simply, the First Law states that energy cannot be created or destroyed; rather, the amount of energy lost in a steady state process cannot be greater than the amount of energy gained.

This is the statement of conservation of energy for a thermodynamic system. It refers to the two ways that a closed system transfers energy to and from its surroundings

Conservation is a non-starter as an idea around here.

Been a while since I took physics. Is gravity still a theory?

Sorry, there is no heat transfer discussed in your link. Heat transfer is simply the transfer of heat from one body to another. Thermodynamics is not about heat transfer, it isn't in one of those equations. Rather thermodynamics is about heat used to create work and energy.

Are you really as dumb as you seem determined to display here? What's your point? They don't hand out prizes for keeping your head in the sand (or other less appealing environments).

The first law states that energy is not created or destroyed, it also states heat cannot go from cold to hot without added energy. This is not heat transfer, non of this will not show how much heat will flow through, for example, an insulated wall VS an uninsulated wall.
