Answer:
27.5°C = Final Temperature of the metal
Explanation:
The change in temperature using the specific heat of a material could be obtained using the formula:
Q = m*S*ΔT
Where Q is heat absorbed in Joules = 128J in the problem
m is the mass of the substance = 10.5g
S is Specific Heat of the substance = 0.449J/g°C for Iron
ΔT is change in temperature = Final T - Initial T
Replacing:
128J = 10.5g*0.449J/g°C*ΔT
2.5°C = ΔT
2.5°C = Final T - 25°C
27.5°C = Final Temperature of the metal
