It takes 130 J. to heat 1 kg of gold per 1 degree Celsius. What is the specific heat of gold?
| September 3, 2021 | education
Initial data: m (weight of gold taken) = 1 kg; Δt (change in gold temperature) = 1 ºС; Q (required amount of heat) = 130 J.
We express the specific heat of gold from the formula: Q = Cg * m * Δt, whence Cg = Q / (m * Δt).
Calculation: Cs = 130 / (1 * 1) = 130 J / (kg * ºС).
Answer: The estimated specific heat of gold is 130 J / (kg * ºС).
