WebApr 5, 2024 · (a) Joule's law of heating states that power of heating generated by an electrical conductor is proportional to the product of its resistance (R) and square of the … WebHeating requirements vary based on the type of building and heating system: For residential buildings with central (shared) heating equipment and no central cooling (air …
WebIt can be represented mathematically as. Δ Q = Δ U + W. Where, ΔQ is the heat given or lost. ΔU is the change in internal energy. W is the work done. We can also represent the above equation as follows, Δ U = Δ Q − W. So we can infer from the above equation that the quantity (ΔQ – W) is independent of the path taken to change the state.
