How many degrees the temperature of copper weighing 1 kg will rise if it receives 160 kJ.
| July 3, 2021 | education
Task data: m (mass of taken copper) = 1 kg; Q (the amount of heat that copper received) = 160 kJ (160 * 10 ^ 3 J).
Reference values: Cm (specific heat of copper) = 400 J / (kg * K).
The temperature rise of taken copper can be expressed from the formula: Q = Cm * m * Δt and Δt = Q / (Cm * m).
Calculation: Δt = 160 * 10 ^ 3 / (400 * 1) = 400 ºC.
Answer: After receiving 160 kJ of heat, the temperature of copper will rise by 400 ºC.
