To heat 2 * c gold with a mass of 0.004 tons, 3040 J is consumed. What is the specific heat of gold?

Task data: Δt (required change in gold temperature) = 2 ºС; m (weight of gold) = 0.004 t (4 kg); Q (consumed amount of heat energy) = 3040 J.

We determine the specific heat of gold from the formula: Q = Cg * m * Δt and Cg = Q / (m * Δt).

Calculation: Cs = 3040 / (4 * 2) = 380 J / (kg * ºС).

Answer: Gold, according to the calculation, has a specific heat capacity of 130 J / (kg * ºС), but the obtained value corresponds not to the specific heat capacity of gold, but to tin bronze.
