Describe COHESION.
Water molecules attracted to other substances.
Water molecules climbing upwards against the force of gravity.
Water molecules dissolving many substances because of its polarity.
Water molecules attracted to other water molecules.
Refer to the picture of water sticking to a leaf; this is occurring because of:
Adhesion
Cohesion
Surface tension is the property of water in which...
water molecules at the surface tend to stick together.
water spills easily.
water tends to be see-through.
tendency of molecules of the same kind to stick to one another
cohesion
adhesion
solution
polar molecule
Water droplets take a spherical shape (as pictured) because of ____________
adhesion
cohesion
capillary action
solubility
Water beads up on the surface of a penny because of this property.
Adhesion
High Surface Tension
Universal Solvent
Changes in Density
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
Water's ability to stick to glass is
adhesion
cohesion
surface tention
capillary action
What is adhesion?
Water's ability to stick to itself
Water's ability to stick to other substances
The strength of the cohesion of all the water molecules combined
Tape, glue and other adhesives
Water droplets on a spider web are an example of....
density
surface tension
adhesion
cohesion
Water sticks to itself.
density
surface tension
adhesion
cohesion
Water droplets joining together to make one large water droplet.
density
surface tension
adhesion
cohesion
A water strider (bug) going across the water is an example of
surface tension
cohesion
adhesion
lesions
Water molecules stick together forming a "skin" on water known as ______ _________ allowing light objects to float.
hydrogen bonding
opposites attract
surface tension
polar molecule
Surface tension also allows water to move through plants roots and stems and small blood vessels. As one molecule moves up the root or vessel, it pulls the other. This movement is referred to as ____________ ____________?
polar molecules
surface tension
hydrogen bonding
capillary action
Why does water form a curved surface in a glass tube?
Gravity pulling it down
The tube's color
Cohesion among water molecules
Adhesion between water and glass
How would you use the concept of adhesion and cohesion to explain the movement of water in a thin tube?
Adhesion allows water to stick to the tube's surface, while cohesion pulls more water along
Cohesion allows water to stick to the tube's surface, while adhesion pulls more water along
Both adhesion and cohesion repel water from the tube's surface
Neither adhesion nor cohesion affects water movement in tubes
How does surface tension benefit small organisms like water striders?
It allows them to sink and retrieve food from underwater
It enables them to walk on the water surface without sinking
It helps them to swim faster
It makes the water less dense
