How much energy is required to heat 500 grams of iron by 14 degrees?
| February 24, 2021 | education
These problems: m (weight of iron taken) = 500 g (0.5 kg); Δt (required change in iron temperature) = 14 ºС.
Reference values: Szh (specific heat capacity of iron) = 460 J / (kg * ºС).
The amount of heat energy for heating iron is determined by the formula: Q = Czh * m * Δt.
Calculation: Q = 460 * 0.5 * 14 = 3220 J.
Answer: To heat iron by 14 ºС, 3220 J of thermal energy is required.
