Answer:
33.3 J
Explanation:
From the question above,
Q = cm(Δt)................... Equation 1
Where Q = Amount of heat, c = specific heat capacity of iron, m = mass of iron, Δt = change in temperature.
Given: c = 0.444 J/g°C, m = 50 g, Δt = 15 °C
Substitute these values into equation 1
Q = 0.444(50)(15)
Q = 33.3 J
Hence the amount of heat need is 33.3 J
