WorksheetsProperties of Water:Cohesion and adhesion
Total questions: 15
Worksheet time: 8mins
Surface tension of the water is the cohesive force between water molecule on the surface of water.
True
False
Why can water striders walk across the surface of water without falling through?
They are light enough so they don't break the hydrogen bonds holding the water molecules together
The insects actually use their wings to hover slightly above the water’s surface
The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
Refer to the picture; the water is sticking to the spider web because of:
Adhesion
Cohesion
Refer to the picture; the water droplets are sticking to the leaf because of:
Adhesion
Cohesion
hydrophillic
tending to repel or fail to mix with water
tendency to dissolve or mix with water
a liquid mixture where a minor component is distributed with a major component
minor component in a mixture
hydrophobic
tending to repel or fail to mix with water
tendency to dissolve or mix with water
a liquid mixture where a minor component is distributed with a major component
minor component in a mixture
universal solvent
the tendency of a liquid to rise or fall as a result of surface tension
creates skin-like surface formed due to the polar nature of water
property of water that enables it to dissolve more substances than any other liquid
the heat required to raise the temperature of a given substance by a given amount
