Answer:
1792 J.
Explanation:
- To calculate the energy would a jeweler need, we use the relation:
The amount of heat released from Cu = Q = m.c.ΔT.
where, m is the mass of Cu (m = 4.4 g).
c is the specific heat capacity of Cu = 0.385 J/g°C.
ΔT is the temperature difference = (final T - initial T = 1083°C - 25°C = 1058°C).
∴ The amount of heat released from Cu = Q = m.c.ΔT = (4.4 g)(0.385 J/g°C)(1058°C) = 1792 J.
