The right formula to use for this calculation is the heat capacity formula,
Heat absorbed, Q = MCT, Where
M = Mass of the substance = 71
C = Specific heat capacity for iron = 0.450 J/gc
T = Change in temperature = 29 - 11 = 18
Q = 71 * 0.450 *18 = 575.10
The amount of heat absorbed by the iron skillet is 575 J.
Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
The most exact answer is 78.4J also in this kind of options we can say answer "d"
