Investigation B, Step 2 only is the one in which a chemical change will most likely occur and is denoted as option D.
<h3>What is Chemical change?</h3>
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.

Answer:One mile is also equal to 5,280 feet or 1,760 yards. The mile is a US customary and imperial unit of length. Miles can be abbreviated as mi, and are also sometimes abbreviated as m. For example, 1 mile can be written as 1 mi or 1 m. Inches. An inch is a unit of linear length measure equal to 1 / 12 of a foot or 1 / 36 of a yard.
Explanation:
It may have less attractive forces between their atoms
Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.
<h3>What is meant by Boiling Point ?</h3>
The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.
Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C
The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.
The OH group in alcohol allows molecules to engage in hydrogen bonding.
Therefore Boiling point are in the order ;
Alcohol > alkane > ethers
