How is heat produced
Web1) In a transfer of energy as heat without work being done, there are changes of entropy in both the surroundings which lose heat and the system which gains it. The increase, Δ S , of entropy in the system may be considered to consist of two parts, an increment, Δ S ′ that matches, or 'compensates', the change, −Δ S ′ , of entropy in the surroundings, and a … Web27 aug. 2013 · The same current flows in one end of a wire that flows out the other end, regardless of how much heat is dissipated in the wire (or any other resistor). Energy is conserved because the resistance times the current causes a voltage drop. This voltage times current is power, which is taken from the circuit and heats the resistor.
