Adam Hart-Davis/Photo Researchers, Inc. In the above image, a paperclip appears to be resting on the surface of a cup of water at room temperature. Nothing has been added to the water to accomplish this. Which one of the following statements accurately describes why this effect is possible? O The strength of the hydrogen bonds between the molecules of water are stronger than the weight of the paperclip (if the paperclip is carefully placed so that it does not break the surface, which would break hydrogen bonds). The paperclip sits on the surface of the water, which acts like a rubber sheet. O Water can break down into hydrogen and hydroxide ions. These ions repel the metal of the paperclip. This is also why metal ships can float. O Even though the paperclip is made of metal, which usually sinks in water, smaller objects (such as paperclips or very small rocks) are more likely to float than are larger chunks of material.

In the above image, a paperclip appears to be resting on the surface of a cup of water at room temperature. Nothing has been added to the water to accomplish this. Which one of the following
statements accurately describes why this effect is possible?
O The strength of the hydrogen bonds between the molecules of water are stronger than the weight of the paperclip (if the paperclip is carefully placed so that it does not break the
surface, which would break hydrogen bonds). The paperclip sits on the surface of the water, which acts like a rubber sheet.
O Water can break down into hydrogen and hydroxide ions. These ions repel the metal of the paperclip. This is also why metal ships can float.
O Even though the paperclip is made of metal, which usually sinks in water, smaller objects (such as paperclips or very small rocks) are more likely to float than are larger chunks
of material.
