When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?
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 key for
Water moving from roots to leaves in plants
Air moving from mouth to lungs
Ice floating on water
If this is a floating ice sheet, which property of water is this polar bear relying on?
Surface Tension
Cohesion
Adhesion

Covalent bonding within water molecules
Ionic bonding with other substances
Van der Waals forces
How does the high specific heat capacity of water affect Earth's climate?
It causes rapid temperature changes
It stabilizes ocean temperatures
It increases evaporation rates
It decreases humidity levels
What is the effect of water's polarity on its ability to dissolve salts?
It allows water to form hydrogen bonds with salts
It allows water to break ionic bonds in salts
It prevents water from interacting with salts
It makes water less effective at dissolving salts
