Question
Alice is investigating how the amount of salt added to water affects its boiling point Which would be a suitable hypothesis for her experiment? The longer the water is heated for, the higher the boiling point. The boiling point will change. The amount of salt will affect the boiling point. The amount of salt will not have an effect.

Answer
The amount of salt will affect the boiling point.
Explanation
## Step 1:The first step in formulating a suitable hypothesis for Alice's experiment is understanding the context of the experiment. Alice is investigating how the amount of salt added to water affects its boiling point. This means she is trying to understand the relationship between the amount of salt and the boiling point of water.## Step 2:A hypothesis is a proposed explanation for a phenomenon, which can be tested through experiments. It should be specific and directly related to the variables being investigated. In this case, the variables are the amount of salt and the boiling point of water.## Step 3:Looking at the given options, we can eliminate the first one ("The longer the water is heated for, the higher the boiling point.") because it doesn't relate to the variables Alice is investigating. The second option ("The boiling point will change.") is too vague and doesn't specify how the boiling point will change. The fourth option ("The amount of salt will not have an effect.") contradicts the purpose of Alice's experiment, which is to investigate if the amount of salt does have an effect.## Step 4:The third option ("The amount of salt will affect the boiling point.") is a suitable hypothesis for Alice's experiment. It directly relates to the variables Alice is investigating (amount of salt and boiling point of water) and is specific enough to be tested through an experiment.
