<em>If a drop of dishwashing detergent is added near it, the paperclip most likely will;</em>
Soap is a surfactant that disrupts the intermolecular forces of water making the paperclip sink.
<u>The paperclip is able to float on the surface of water due to its surface tension. </u>
<u>When soap is added to water, it reduces the surface tension. Soap disrupts the intermolecular forces that hold the molecules on the surface tightly like a film. </u>
<u>Thus, the paperclip sinks into the water.</u>
Answer: all other conditions equal, the rate evaporation of a contained liquid will be slower than the rate of evaporation of an uncontained liquid.
Justification:
1) The rate of evaporation increases as the surface area of the liquid (relative to the whole content) increases. This is, the greater the surface is the faster the evaporation.
2) That is so because the higher the surface of the liquid the more the number of particles in the liquid that are in contact with the surrounding air and so the more the particles will escape from the liquid to the air (which is what evaporation is).
3) A liquid contained will take the form of the container, so part of the liquid wil remain below the surface, while an uncontained liquid will spread all over the surface and so pratically all the liquid is in contact witht the air surrounding it.
In oil and gas industry:
When crude oil get extracted from well, salt water and some other stuff needs to be removed before oil can be sued in the car
