The specific heat (SH) of a substance is the amount of heat (q), in joules or calories, needed to change the temperature of 1 g of the substance by exactly 1°C. The equation and units for specific heat are provided below: SH = qm × ΔT = Jg. °C The heat equation is used to determine the quantity of heat (q) absorbed or lost by a substance. It is derived from the specific heat relationship by multiplying both sides by m and ΔT: q = m × ΔT × SH Some homes that use baseboard heating use copper tubing. Hot water runs through and heats the copper tubing, which in turn heats aluminum fins. It is actually the aluminum fins that heat the air rising through the fins. How much energy would it take to heat a section of the copper tubing that weighs about 475.0 g , from 15.21 °C to 23.23 °C? Copper has a specific heat of 0.3850 (J/g)°C.
