Water beads up on the surface of a penny because of what property?
Erosion
High surface tension
Universal solvent
Changes in density
Which statement explains why water molecules stick together?
Both sides are negative
One side has a positive charge and the other side has a negative charge
One side has a negative charge and the other side has a neutral charge
Both sides are positive
Large bodies of water help to keep nearby climates from being too hot or too cold because they
Absorb heat in the spring and slowly release that heat in the fall
Absorb heat in the fall and slowly release that heat in the spring
Absorb heat in the summer and slowly release that heat in the winter
Absorb heat in the winter and slowly release that heat in the summer
Even though 75% of Earth's surface is covered in water only 1% of that water is usable:

Magic
At what temperature does water Freeze?
0o C
100o C
32o C
-273o C
A water strider can skate along the top of a pond because:
covalent bonds result in water cohesion (surface tension)
hydrogen bonds result in water cohesion (surface tension)
water striders have adapted to take advantage of water cohesion
water striders are afraid of water and avoid it
At what temperature does water Boil?
0o C
100o C
32o C
212o C
Why does ice float?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it
Capillary action is the result of waters properties of cohesion and adhesion working together to allow water to...
Absorb water through the roots of plants
Stick to other things
Stick to itself
Flow upward against the force of gravity
Capillary Action is key for
Water moving from roots to leaves in plants
Air moving from mouth to lungs
Ice floating on water
Water moving to lower areas
