what is meant by saing taht latent heat of fusion of ice is 3.34 x 10⁵ J /kg

Solution

For ice, the latent heat of fusion means that 334 kJ of heat is required to convert 1 kg of ice at 0ºC into 1 kg of water at 0ºC. Conversely, 334 kJ of heat is released when 1 kg of water freezes at 0ºC to give 1 kg of ice at 0ºC.

1 kg of ice at $0^{\circ} C$ is mixed with 1 kg of steam at $100^{\circ} C$ . What will be the composition of the system when thermal equilibrium is reached? Latent heat of fusion of ice = $3.36 \times 10^{5} J k g^{- 1}$ and latent heat of vaporization of water = $2.26 \times 10^{6} J k g^{- 1}$

Why is the latent heat of fusion of ice i.e 3.34×10⁵J/kg less than the latent heat of vapourisation i.e 22.5×10⁵J/kg? Particles of solids are more tightly packed than liquids so literally the should require more energy for separation than liquids.
