The amount of heat for this process is calculated using the enthalpy of fusion (6.0 kJ/mol), making it 12.0 kJ for 2.00 moles of water. Throughout this process, the temperature remains at 0°C. Explanation: Aug 16, 2023 · Melting is a process that causes a substance to change from a solid to a liquid. Melting occurs when the molecules of a solid speed up enough that the motion overcomes the attractions so that the molecules can move past each other as a liquid. Summary. Students will see a small piece of ice melt on an aluminum surface. Crystals consisting of particles with stronger attractive forces melt at higher temperatures. The amount of heat required to change one mole of a substance from the solid state to the liquid state is the enthalpy of fusion, ΔH fus of the substance. The enthalpy of fusion of ice is 6.0 kJ/mol at 0 °C. Fusion (melting) is an endothermic process:Gold metal is formed from gold chloride in solution.
