To find out the cost of heat for heating the taken copper, we use the formula: Q = CCu * m * (t – t0), where CCu is the specific heat of copper (taken CCu = 385 J / (kg * K)); m is the mass of copper taken (m = 100 g; in the SI system m = 0.1 kg); t – required temperature (t = 85 ºС); t0 – temperature before heating (t0 = 15 ºС).
Let’s calculate: Q = CCu * m * (t – t0) = 385 * 0.1 * (85 – 15) = 2695 J.
Answer: To heat 100 g of taken copper, 2695 J of heat should be required.
