What amount of heat is absorbed when melting by ice with a mass of 5 kg taken at a temperature of 0 ° the specific heat of melting of ice is 340 k J / kg
Task data: m (ice mass) = 5 kg; t (temperature at which the ice was located) = 0 ºС (melting point).
Reference data: according to the condition λ (specific heat of melting of ice) = 340 kJ / kg (340 * 10 ^ 3 J / kg).
The amount of heat that ice will absorb during melting is determined by the formula: Q = λ * m.
Calculation: Q = 340 * 10 ^ 3 * 5 = 1.7 * 10 ^ 6 J (1.7 MJ).
Answer: When melting, ice must absorb 1.7 MJ of heat.
