Answer:
66124.8 J
Explanation:
Using the formula;
Q = m × cp × ∆T
Where;
Q = change in heat (J)
m = mass of substance (g)
cp = specific heat capacity (4.184 J/g°C)
∆T = change in temperature (°C)
According to this question,
Q = ?
m = 54.31 grams
∆T (final - initial temperature) = 438°C - 147°C = 291°C
cp = 4.184 J/g°C
HENCE,
Q = m × cp × ∆T
Q = 54.31 × 4.184 × 291
Q = 66124.8 J
