How much heat is required to turn 10 kg of ice into water at 0 degrees?
August 31, 2021 | education|
Ice is at the melting temperature and heat is consumed only for the transition of ice to a liquid state of aggregation; additional heating of water after transformation, according to the condition of the problem, is not required.
Q = λ * m, where λ is the specific heat of melting (for ice λ = 3.4 * 10 ^ 5 J / kg), m is the mass of ice (m = 10 kg).
Let’s calculate the heat:
Q = λ * m = 3.4 * 10 ^ 5 * 10 = 3.4 * 10 ^ 6 J = 34 MJ.
Answer: To convert 10 kg of ice into water, 34 MJ of heat is required.
