The change in temperature of an iron bar brought about by a transfer of heat is given by AT= AQ/mc, where AQ is the amount of heat transferred, m is the mass of the bar, and c is the specific heat of iron. Assume that c = 448 J/kg°C and AQ=1210 J are known with negligible uncertainty. Assume the mass is m = 0.52 ± 0.03 kg. Estimate AT, and find the uncertainty in the estimate. (Round the final answers to four decimal places.) The estimated change in temperature is The uncertainty in the estimated temperature is °C. °C.
