How much heat is needed to melt 5 kg of ice taken at a temperature of 0 degrees?
June 27, 2021
The amount of heat that will go to melt 5 kg of ice can be calculated using the formula:
Q = λ * m, where λ is the specific heat of melting of ice (λ = 3.4 * 10 ^ 5 J / (kg * K)), m is the mass of ice (m = 5 kg).
Let’s calculate the required amount of heat:
Q = λ * m = 3.4 * 10 ^ 5 * 5 = 17 * 10 ^ 5 J = 1.7 MJ.
Answer: To melt 5 kg of ice, you need to spend 1.7 MJ of heat.
