How much heat is required to heat 10 kg of zinc at 3 ° C?

univerkov | June 22, 2021 | education

Initial data: m (mass of heated zinc) = 10 kg; Δt (change in zinc temperature) = 3 ºС.

Reference values: C (specific heat capacity of zinc) = 400 J / (kg * K).

The required amount of heat for heating zinc to a given temperature is determined by the formula: Q = C * m * Δt.

Let’s calculate: Q = 400 * 10 * 3 = 12,000 J or 12 kJ.

Answer: To heat 10 kg of zinc at 3 ºС, 12 kJ of heat is required.
