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.

Determine the effect that hydrogen bonding has on the physical properties of water.
Andrews [41]
<span>Water can absorb high amounts of heat before there is an observed rise in temperature. It has the highest heat capacity among all liquids. This is caused by the presence of hydrogen bonding in water molecules which gives it stronger attraction between the molecules.</span>

What does lead ii acetate and hydrogen sulfide produce? and what type of reaction is it?
kati45 [8]
When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS
