For heating a piece of zinc weighing 5 kg by 10 degrees, an amount of heat equal to 20 kJ

For heating a piece of zinc weighing 5 kg by 10 degrees, an amount of heat equal to 20 kJ is required. what is the specific heat of zinc?

The amount of heat required to heat zinc can be calculated using the formula:
Q = C * m * ∆t, where Q is the amount of heat expended on heating zinc (Q = 20 kJ = 100 * 10³ J), C is the specific heat capacity of zinc (J / (kg * K)), m is the mass of zinc ( m = 5 kg), ∆t – change in zinc temperature (∆t = 10 ºС).
Let us express and calculate the specific heat of zinc:
С = Q / (m * ∆t) = 20 * 10³ / (5 * 10) = 400 J / (kg * K).
Answer: The specific heat capacity in zinc is 400 J / (kg * K).
