Answer:
18.3 J
Explanation:
Heat required to raise the temperature of copper from 27.6°C to 38°C is given by
Q = mCΔT
m = mass of Copper = 13.5 g
C = Specific heat capacity of Copper = 0.13 J/g.°C
ΔT = change in temperature of Copper = 38 - 27.6 = 10.4°C
Heat = 13.5 × 0.13 × 10.4 = 18.25 J = 18.3 J to 3s.f
