| **An ice block weighing 15 kg cooled by 10 degrees C overnight. The specific heat capacity of ice is 2100 J / kg * C. How much energy is required to heat the ice to its original temperature?**

The amount of heat required to heat the ice to its original temperature can be calculated using the formula:

Q = C * m * ∆t, where Q is the amount of heat expended on ice heating (J), C is the specific heat capacity of ice (C = 2100 J / (kg * K)), m is the mass of the ice block (m = 15 kg ), ∆t is the change in the temperature of the ice block (∆t = 10 ºС).

Let’s calculate the required amount of heat:

Q = C * m * ∆t = 2100 * 15 * 10 = 315000 J = 315 kJ.

Answer: To heat an ice block, 315 kJ of heat is needed.
