Heat of Fusion is defined as the energy required to turn a liquid into a solid, or said phase changing latent heat. In this case the only choice that represents that phase change is (1). Where the heat removed to turn a liquid of a substance into it's solid form is instead added to excite the bonds and liquify it. Yet, heat of fusion (s) ->(l)
is still the same as going from liquid to solid just one is adding and the other is removing, respectively.
Answer: Compound . Chemical reactions can divide elements into simpler substances, but they cannot separate elements into simpler substances. Physical or chemical characteristics of substances can be categorised.
Compounds and elements can be created from pure substances. A chemical reaction is required to break down pure substances (elements and compounds) into their component atoms or elements. This is known as the chemical separation process. Physical separation of pure substances is impossible.
Explanation:
What makes something pure substance?
One element or a small number of related compounds make up pure substances. Mixtures are assemblages of many components. Mixtures of two or more substances (or elements) that cannot be visually distinguished from one another are referred to as homogeneous mixtures.

A substance made up of two or more components is called a compound. Table salt, water, and carbon dioxide are a few examples of compounds
