How will the temperature of copper change for a rod weighing 150 g if 24 J of energy is transferred to it? The specific heat of copper is 400 J / kg.
Initial data: m (mass of a copper rod) = 150 g = 0.15 kg; Q (the amount of heat transferred to the rod) = 24 J.
Reference values: by condition C (specific heat of copper) = 400 J / (kg * K).
The temperature change of the copper rod is determined from the formula: Q = C * m * Δt, whence Δt = Q / (C * m).
Let’s calculate: Δt = 24 / (400 * 0.15) = 0.4 ºС.
Answer: The temperature of the copper rod will increase by 0.4 ºC.
