Which side of the water molecule has a slightly negative charge?
It's all negative
It's all positive
Hydrogen
Oxygen
Which property of water allows it to dissolve many substances?
High surface tension
Polarity
Low density
High boiling point
Which property of water contributes to its ability to form droplets?
High surface tension
Low boiling point
High density
Polarity
What causes water to expand when it freezes?
Increased molecular motion
Formation of a crystalline structure
Decreased hydrogen bonding
Increased density
What is the primary reason ice floats on water?
Ice is denser than water
Ice has a crystalline structure
Ice is less dense than water
Ice has more hydrogen bonds
Which property of water allows it to climb up plant roots and stems?
Adhesion
High boiling point
Low density
High surface tension
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
If this is a floating ice sheet, which property of water is this polar bear relying on?
Surface Tension
Cohesion
Adhesion
Density
Capillary Action is important for
Water moving from roots to leaves in plants
Air moving from mouth to lungs
Ice floating on water
Water moving to lower areas
Adhesion means ...
Cohesion means ....
Water striders can walk on water because of (a) .
Mixing sugar into your coffee/tea is an example of-
adhesion
cohesion
universal solvent
high heat capacity
What are the unique properties of water? - choose all that apply.
cohesion
adhesion
specific heat
universal solvent
unique temperature
Ponds and lakes can act as a (a) for changes in temperature.
Water has a __________________ meaning it takes a lot of heat energy to raise the temperature.
high heat capacity
universal solvent
polarity
density
The reason why it takes so long to boil a pot of water on the stove is because-
low density of ice
high heat capacity of water
strong cohesion between water molecules
strong adhesion between water and the pot
Rain sticking to the windshield is an example of-
