| September 25, 2021 | education
Task data: m (mass of taken aluminum) = 3 kg; Δt (required change in temperature of aluminum) = 50 ºС.
Reference values: Ca (specific heat of aluminum) = 920 J / (kg * K).
The required amount of heat to change the temperature of 3 kg of aluminum is calculated by the formula: Q = Ca * m * Δt.
Calculation: Q = 920 * 3 * 50 = 138 * 103 J (138 kJ).
Answer: To change the temperature of 3 kg of aluminum, 138 kJ of heat is required.
