Heat fusion of ice formula
Web27 de dic. de 2024 · Calculate the heat of fusion of ice having 16000 J heat supplied to its mass of 25 gm. Solution 2. Given that, The heat supplied is 16000 J. The mass of the body is 25 gm. Therefore, the heat of fusion of the body will be, ∆ Hf = Q m ∆ Hf = 16000 25 ∆ Hf = 640J g Example 3. WebLatent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing …

The symbol of the heat of fusion is ΔHf. The formula of the heat of fusion is ΔHf = q/m or q = m·ΔHf (both are the same, anyhow). Note: the temperature does not really change when matter changes its state, so the temperature is not in the equation or required for the calculation. The melting of helium is the only exception.
