To heat 1 kg of gold at 1 ° C, 130 J. is required. What is the specific heat of gold?

Initial data: m (mass of gold taken) = 1 kg; Δt (change in gold temperature) = 1 ºС; Q (amount of heat required) = 130 J.
The specific heat of gold is expressed from the formula: Q = Cz * m * Δt, whence Cz = Q / (m * Δt).
Calculation: Cz = 130 / (1 * 1) = 130 J / (kg * ºС).
Answer: The estimated specific heat of gold is 130 J / (kg * ºС).
