Question

Malia was able to make a paperclip float on the surface of water. What will most likely happen to the paperclip if a drop of dishwashing detergent is added near it?
Soap is a surfactant that increases the intermolecular forces of water allowing the paperclip to continue to float.
Soap makes the water less viscous making the paperclip sink.
Soap is a surfactant that disrupts the intermolecular forces of water making the paperclip sink.
Soap makes the water more viscous allowing the paperclip to continue to float.

Answer 1

Soap is a surfactant that disrupts the intermolecular forces of water making the paperclip sink.

Explanation: the paperclip floats because surface tension (cohesion of water molecules) supports it. Detergent molecules reduce water's surface tension by inserting between water molecules, so the surface can no longer support the paperclip and it sinks.
