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.
Refer to the picture of water sticking to a leaf; this is occurring because of:
Adhesion
Cohesion
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.
Water's ability to stick to glass is
adhesion
cohesion
surface tention
capillary action
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
Water sticking to the paper clips is called -
cohesion
(a) is water droplets sticking to each other. (b) is water droplets sticking to other surfaces.
Water has good __________ which can be seen when insects and leaves are able to sit on top of water.
synergistic effects
balance
surface tension
photosynthesis
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
