If water has a molar heat of fusion of 6.02 kJ/mol, 18.06 kJ of energy is required to dissolve 3 moles of ice.
The enthalpy of matter changes with the heat of fusion releasing energy.
To change a substance from solid to liquid while maintaining pressure, a certain amount of substance must be used.
Enthalpy, a property of a thermodynamic system, is calculated by adding the internal energy of the system to the product of pressure and volume. It is the heat of the molten state used in numerous measurements at constant pressure in chemical, biological, and physical systems. called enthalpy
1 mol melts at a heat of 6.02 KJ.
The heat required to melt 3 moles is 6.02 kJ * 2.56 = 18.06 kJ.
