To find the heat released during the cooling of a given copper body, we use the formula: Q = Cm * m * Δt.

Values of constants and variables: Cm – specific heat capacity of copper (Cm = 400 J / (kg * K)); m is the mass of the body made of copper (m = 4 kg); Δt – change (decrease) in temperature.

Let’s make a calculation: Q = Cm * m * Δt = 400 * 4 * 20 = 32 * 10 ^ 3 J (32 kJ).

Answer: When a given copper body cools down, 32 kJ of heat should be released.
