Water is a ____________ molecule meaning it contains a slightly positive and negative charge
In a water molecule, the oxygen atom is
Negatively charged
neutral (no charge)
both positively and negatively charged
positively charged
Cohesion occurs when water molecules
stick to other water molecules
are attracted to other materials
stick to a table top
are attracted to a the same charge
Which of the following scenarios is an example of cohesion
water sticks to the walls of blood vessels
water molecules stick to the surface of a mirror
water molecules stick to one another and form a puddle
Why does ice (solid water) float in liquid water?
Solid water is more dense than liquid water
Solid water is less dense than liquid water
Adhesion occurs when water molecules
stick to other water molecules
are pulled apart
stick to other substances
none of these are true
Water has a high heat capacity; this means
it doesn't take a LOT of heat to heat water
the bottom of the ocean is colder
it takes a LOT of heat to heat up water
oceans don't freeze solids
Certain insects "walk on water" because of water's?
adhesion
surface tension
this is a false statement
capillary action
Water is known as the "universal solvent". This means
It is necessary for life
It is found almost anywhere
It exists as a liquid at room temperature
It can dissolve many other substances
Water is able to travel against the flow of gravity using capillary action. What causes this?
photosynthesis & cohesion
cohesion & adhesion
adhesion & surface tension
surface tension & photosynthesis
