Question 1 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?
O A. Add more liquid to the larger vials so that they come up to the
same height
B. Add a few drops of salt to the larger vials to increase the surface
tension of the liquids.
C. Add a few drops of salt to the smaller vials to increase the surface
tension of the liquids,
D. Use vials that are the same size, and wash and dry them well in
between uses.
