What is the specific heat of aluminum, if 200 g of aluminum was heated to 10C to obtain 1800J of heat.

These tasks: Q (heat spent on heating the taken aluminum) = 1800 J; m (weight) = 200 g (in SI m = 0.2 kg); Δt (temperature change of aluminum during heating) = 10 ºС.

We express the specific heat of aluminum from the formula: Q = Ca * m * Δt, whence Ca = Q / (m * Δt).

Let’s calculate: Ca = 1800 / (0.2 * 10) = 900 J / (kg * K).

Answer: Aluminum, according to the calculation, has a specific heat equal to 900 J / (kg * K).
