Answer:
The specific heat of magnesium is 1.02 J/g.K
Explanation:
To calculate the energy involved in the heating of the metal (magnesium), we use the following expression:
energy = mass x Cp x ΔT
We have the following data:
mass = 2.00 kg x 1000 g/1.00 kg = 2000 g
energy = 8160 J
ΔT = 4 K
Thus, we can calculate the specific heat of magnesium (Cp) in J/g.K as follows:
⇒ Cp = energy/(mass x ΔT) = 8160 J/(2000 g x 4K) = 1.02 J/g.K
