| July 13, 2021 | education
What amount of heat is absorbed by ice with a mass of 5 kg when melting if its temperature is 0 ° C? The specific heat of melting of ice is 340 kJ / kg
Formula for finding the amount of heat released during ice melting:
Q = lambda × m.
Lambda – specific heat of melting of ice, J / kg.
m – ice mass, kg.
Lambda is a tabular value and it is equal to 340 kJ / kg.
Ice weight 5 kg.
Q = 340 × 10 ^ 3 J / kg × 5 kg = 1700 × 10 ^ 3 J = 1.7 MJ.
Answer: the amount of heat released during ice melting is 1.7 MJ.
