The amount of heat Q required to heat a body of mass m, which has an initial temperature t₁ to a temperature t₂:
Q = c (t₂ – t₁) m,
where c is the specific heat.
Substitute the values from the condition and tabular data:
Q = 880 J / (kg • deg) * (30 ° C – 15 ° C) * 4 kg = 52 800 J.
Answer: 52 800 J.
