What amount of heat is needed for heating copper weighing 2 kg 10 kg by 1 C.

The amount of heat for heating copper is calculated by the formula:
Q = C * m * ∆t, where C is the specific heat capacity of copper (C = 385 J / (kg * K), m is the mass of copper (kg), ∆t is the change in copper temperature (∆t = 1 ºС).
Heat for heating 2 kg of copper:
Q = C * m * ∆t = 385 * 2 * 1 = 770 J.
Heat for heating 10 kg of copper:
Q = C * m * ∆t = 385 * 10 * 1 = 3850 J = 3.85 kJ.
Answer: It is necessary to spend 770 J and 3.85 kJ of heat, respectively.
