Answer : The specific heat of metal in this case will be 0.411 J/g°C
Explanation : Specific heat can be calculated by using the formula
Q = CmΔT
where Q is heat added which is 100 here
C is specific heat which needs to be found
m is mass of the metal
and ΔT is the temperature change
on substituting we get,
100 = x . 60 . 4.05
so, x = 0.411
