Given: m (ice mass) = 3 kg; t (temperature at which the ice was before the heat was delivered) = 0.0 ºС (corresponds to the temperature of the beginning of the melting process).
Constants: λ (specific heat of fusion) = 3.4 * 10 ^ 5 J / kg.
The amount of heat required to melt ice will be equal to the product of its mass and specific heat of melting: Q = λ * m.
Calculation: Q = 3.4 * 10 ^ 5 * 3 = 10.2 * 10 ^ 5 J.
Answer: To melt 3 kilograms of ice, you need 10.2 * 10 ^ 5 J of heat.
