The difference between the heat of fusion and the heat of vaporization is that melting only needs a minimal amount of energy to cause molecules to break free from their positions in the crystal lattice while maintaining other molecular interactions.

How is the heat of fusion different from the heat of vaporization?

The energy required for one gram of a solid to melt without experiencing any temperature change is known as the heat of fusion. The amount of energy required for one gram of a liquid to evaporate (boil) without a change in pressure is known as the heat of vaporization.

What happens to heat energy during fusion?

It is possible to heat solids to the point at which the molecules holding their bonds together separate and turn the solid into a liquid. The most typical illustration is when solid ice transforms into liquid water. The molecules within the substance become less structured as a result of this process, which is also known as melting or heat of fusion.

A box of cleaning supplies weighs 15 N. If the box is lifted a distance of 0.60 m, how much work is done?
Nady [450]
Work Done = force x displacement. So in this case the 15N is the force (because weight is a force) and 0.60m is the displacement. Therefore 15 x 0.6 = 9 Joules of work done (btw, work done can also be referred to as energy transferred)
