Answer:
1192.54 J
Explanation:
Applying,
Q = cm(t₂-t₁)................ Equation 1
Where Q = Amount of heat lost, c = specific heat capacity of the iron, m = mass of the iron, t₁ = initial temperature, t₂ = final temperature.
From the question,
Given: m = 83 g = 0.083 kg, t₁ = 297 K, t₂ = 329 K
Constant: c = 449 J/kg.K
Substitute these values into equation 1
Q = 449(0.083)(329-297)
Q = 449(0.083)(32)
Q = 1192.54 J
