Final answer:
The mechanics of a hot sugar-free Cocomo refer to the chemical reactions that occur when the ingredients are heated, specifically caramelization. Artificial sweeteners or natural sugar substitutes are used instead of regular sugar.
Step-by-step explanation:
In the context of a hot sugar-free Cocomo, the mechanics refer to the chemical reactions that occur when the ingredients are heated. When sugar is heated, it undergoes a process called caramelization, where sucrose molecules break down into simpler sugar molecules, resulting in the characteristic caramel flavor. In the case of a sugar-free Cocomo, artificial sweeteners or natural sugar substitutes are used in place of regular sugar.
