NEED HELP

questlon 2 of 10 When he designed his experiment, Marcos found that he had three small vials of the same size and two slightly larger ones. He did not think that the vials were close enough in size to use them all at once in comparing the properties of the different liquids. How could he solve this problem?

A. Add a few drops of salt to the smaller vials to increase the surface tension of the liquids.

B. Add a few drops of salt to the larger vials to increase the surface tension of the liquids.

C. Use vials that are the same size, and wash and dry them well in between uses.

D. Add more liquid to the larger vials so that they come up to the same height​

Answer 2

"Use vials that are the same size, and wash and dry them well in between uses". The correct answer is option C.

To solve the problem of having vials of different sizes when comparing the properties of different liquids, Marcos could take the following steps:

1. Use vials that are the same size: By using vials that have the same size, Marcos can ensure that the volume of liquid being compared is consistent across the different vials. This will help in making accurate comparisons of the properties of the liquids.

2. Wash and dry the vials well in between uses: It is important to clean the vials thoroughly before using them for different liquids. This will prevent any contamination and ensure that the properties being measured are solely attributed to the liquids themselves.

By using vials of the same size and maintaining cleanliness between uses, Marcos can overcome the problem of vials of different sizes and conduct a fair and accurate experiment to compare the properties of different liquids.

Option C - "Use vials that are the same size, and wash and dry them well in between uses" - is the correct answer to this question.
