The change in temperature of an iron bar brought about by a transfer of heat is given by ?T=?Q/mc, where ?Q 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 ?Q=1210 J are known with negligible uncertainty. Assume the mass is m=0.54 ± 0.01 kg. Estimate ?T, and find the uncertainty in the estimate.
What will be an ideal response?
