How much heat is required to heat 50 g zinc at 25C?
December 30, 2020
Problem data: m (zinc mass) = 50 g (0.05 kg); Δt (change in temperature of taken zinc) = 25 ºС.
Reference values: SC (specific heat capacity of zinc) = 400 J / (kg * K).
The amount of heat expended to heat the taken zinc is determined by the formula: Q = Cc * m * Δt.
Calculation: Q = 400 * 0.05 * 25 = 500 J.
Answer: To heat the taken zinc, 500 J of heat is required.
