High heat of vaporization of water
Web19 de jul. de 2024 · Water has a high heat of vaporization because of the amount of energy it takes to break the hydrogen bond between the two hydrogen elements and oxygen element. It is important for life to be possible on earth. With out this property of water life wouldn’t exist. Why is the vaporization of water important to the ecosystem? Web31 de ago. de 2024 · When 1 mol of ice, for example, is melted, we find from experiment that 6.01 kJ are needed. The molar enthalpy of fusion of ice is thus +6.01 kJ mol –1, and we can write. H 2O(s)0oC → H 2O(l) Hm = 6.01 kJ mol. Selected molar enthalpies of fusion are tabulated in Table 10.10.1. Solids like ice which have strong intermolecular forces have ...
