Where <em>q</em> is the heat; <em>m</em> is the mass of the substance; <em>C</em> is its specific heat; and Δ<em>T</em> is the change in temperature.
The given specific heat of iron is 462 J/kg -°C.
Substitute and evaluate. Ensure correct units:
Therefore, the block of iron absorbed about 3.5 kJ of heat.
