Question

If you drop a metal paperclip into a cup of water, it will sink to the bottom, however with practice, you can gently place a metal paperclip on the surface and it will balance or appear to float. Why does this happen?
A. Water has strong hydrogen bonds that result in it having strong surface tension allowing the paperclip to float.
B. Due to the polarity of water, the positive hydrogens bond with the paperclip causing it to float on the waters’ surface.
C. The negative ions are attracted to the paper clip allowing it to float.
D. Water has weak hydrogen bonds that cause it to have poor surface tension allowing the paper clip to float.

Answer 1

Answer:

The answer is A because the water has strong surface tension, I didn't know why but I know it's surface tension holding it up so it has to be A

Answer 2

Answer is A
Hopefully this helps!!
