How many joules does it take to melt ice
Web30 sep. 2024 · Answer It takes 4,270 Joules of energy to melt 12.8 grams of ice at 0 °C. Explanation The enthalpy change for melting ice is called the enthalpy of fusion. Its value is 6.02 kJ/mol. This means for every mole of melting ice, we must apply 6.02 kJ of heat. We can calculate the heat needed with the following equation: = Δ where: q = heat Web4 jul. 2016 · ΔH f = 333.55 J g−1 The trick here is to realize that the amount of heat needed to melt ice will be equal to the amount of heat given off when liquid water freezes. You can thus say that when 1 g of water freezes at 0∘C, 333.55 J of heat are being given off to the surroundings. Since your sample has a mass of 295 g, it follows that it will release
