Blood functions as a transport mechanism to take nutrients and oxygen to all cells in the body. What property of water allows for this to occur?
Expansion Upon Freezing
Universal Solvent
Cohesive Behavior
Ability to Moderate Temperature
Describe the movement of the water molecules at cold temperatures.
They join together and move slowly
They move very fast and erratically (疯狂的)
If this is a floating ice sheet, which property of water is this polar bear relying on?
Surface Tension
Cohesion
Adhesion
Density
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
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
Describe the movement of the water molecules at hot temperatures.
