Refer to Exercise 6. Assume that c = 448 J/kgC and Q = 1210 J are known

Refer to Exercise 6. Assume that c = 448 J/kg◦C and ΔQ = 1210 J are known with negligible uncertainty. Assume the mass is m = 0.75 ± 0.01 kg. Estimate ΔT , and find the relative uncertainty in the estimate.

Refer to Exercise 6.

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