Question

Liam and Melinda have completed one trial testing the freezing point of several solutions, but they cannot agree on what to do next in their experiment. What should be the next step in their investigation? A. repetition, completing more trials for each solution B. analysis, determining whether their data and precise and accurate C. further investigation, testing new solutions and comparing them to their original data D. replication, asking about their classmates’ findings to compare data

Answer 1

Answer:

A. repetition, completing more trials for each solution

Explanation:

In this experiment, the two differ in results that is why they ca not agree on the next step.This happens when experimental results do not confirm the hypothesis of the experiment.In such cases, you are required to assess the stages in the experiment which are- the hypothesis, the experimental stages,the analysis stage and the result stage.The key here is to go through the write up of the experiment to see the problems that cause the variations in results.

In this case where they were testing the freezing points of several solutions, there are four cognitive properties of a solution that affects the solvent. They are lowering of vapor pressure, lowering of freezing point, rise in boiling point or initiation of an osmotic pressure in the process.When they perform more trials for each solution, they will see if they carried out the experiment correctly.

Answer 2

Answer:

A. Repetition, completing more trials for each solution

Explanation:

Just got it right on Edg :)
