Question

Investigations were carried out in a science lab to explore the topic of chemical and physical changes.

Answer 1

Investigation B, Step 2 only is the one in which a chemical change will most likely occur and is denoted as option D.

What is Chemical change?

This is referred to as a type of reaction which is characterized by the formation of a new substance as a result of the synthesis or decomposition of a substance which is referred to as the reactant through various methods and techniques.

In the Investigation B, Step 2, the sugar solution is heated on a burner until the solution thickens and turns brown thereby forming caramel. The chemical change in this scenario is depicted as the caramel which is produced in the process known as caramelisation.

There is a new substance formed which is therefore the reason why option D was chosen as the most appropriate choice.
