Which characteristic of water will allow a paperclip to remain floating on water when the paperclip is gently placed on top of the water?

• adhesion

• surface tension

• solvent properties

• nonpolar

Which of the following is an example of COHESION?

• water sticking to water

• water sticking to glass

• oil sticking to plastic

• hydrogen sticking to oxygen

Water sticks well to many materials. What term relates to this property of water?

• cohesion

• adhesion

• density

• surface tension

A water strider can skate along the top of a pond because:

• covalent bonds result in water adhesion (surface tension)

• cohesion allows strong hydrogen bonds in water to form below the surface (surface tension)

• water striders have adapted to take advantage of water cohesion

• water striders are afraid of water and avoid it
