Explanation:
Water dissolves nonpolar covalent substances.
A macromolecule is a very large molecule, such as protein, commonly created by polymerization of smaller subunits (monomers). They are typically composed of thousands of atoms or more. The most common macromolecules in biochemistry are biopolymers and large non-polymeric molecules. :D
Answer: The correct answer is-
liquid to solid.
The term exo in exothermic means outside the system whereas thermic means heat.
Exothermic process can be described as any chemical reaction that liberates energy in the surrounding in the form of heat.
In other words, when heat is liberated in the environment in a chemical reaction, it is said to be an exothermic reaction/process.
When liquid phase changes to solid phase (such as water to ice), heat is released/liberated in the surrounding.
Thus, it is an example of exothermic process.
