What is the equation of heat of fusion?

The equation for the heat of fusion is ΔH=nΔHfus, where "n" is the number of moles and Δ is the molar heat of the substance. The heat of fusion is typically calculated in kilojoules and is represented in mathematical notation as "H."

When a substance melts from a solid state to a liquid state, the heat of fusion is positive. Conversely, when it changes from a liquid to a solid, the heat of fusion is negative. The most common use of the heat of fusion is the melting of ice to water. The industrial applications of the equation for heat of fusion include metal forging, coin making, plastics molding and glassblowing.
