univerkov | April 12, 2021 | education

Initial data: m (mass of heated iron) = 500 g (0.5 kg); Δt (specified change in iron temperature) = 45 ºС.

Reference values: Szh (specific heat of iron) = 460 J / (kg * K).

The amount of heat expended for heating 500 g of iron is determined by the formula: Q = Czh * m * Δt.

Calculation: Q = 460 * 0.5 * 45 = 10 350 J.

Answer: To heat 500 grams of iron, you need to spend 10 350 J of heat.
