The ranking of the metals in terms of how quickly they reach the target temperature are; Pb: 1, Sn: 2, Cu: 3, Fe: 4, Al: 5
Solving Specific Heat Capacity
The formula for quantity of heat from specific heat capacity is;
Q = m * C_s * ΔT
where;
Q is specific heat energy
C_s is specific heat capacity
ΔT is change in temperature
m is mass
Thus, the lower the specific heat or quantity of heat energy, the faster the change in temperature
Making ΔT the subject of the formula gives;
ΔT = Q / ( m * Cs)
We are told that the heat (Q) and mass (m = 100 g) are equal for the five samples. Thus, we have;
ΔT = [Q/m]/C_s
Since Q/m is constant for all the 5 samples, inputting the specific heat capacities means that the higher the specific heat capacity the slower the change in temperature but the lower the specific heat capacity, the quicker the change in temperature.
Solving online means that the fastest to slowest are;
Pb: 1, Sn: 2, Cu: 3, Fe: 4, Al: 5
