# An ice block weighing 15 kg cooled by 10 degrees C overnight. The specific heat capacity of ice

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.
