The ability of a molecule to "stick" to other molecules
Large amounts of energy are required to change the temperature of a substance
A well-organized and efficient team
What characteristic is shown in the image?
Polarity
Hydrogen Bonds
Cohesion
Adhesion
What property of water allows for water to act as a temperature regulator for the world?
Cohesive Behavior
Expansion Upon Freezing
High Specific Heat
Universal Solvent
What word describes when water is attracted to other substances?
cohesion

True or False: Hydrogen bonds are very weak, which allows for many of the chemical characteristics found in water.
True
False
Because of the unique properties of water associated with hydrogen bonding, water evaporates from pores on the leaves of plants and draws water molecules in a continuous chain from the roots up through the vascular tissues of plants. Which of these groups of terms describes the process and the properties of water that explain this?
adhesion, cohesion, and translocation
adhesion, cohesion, and transcription
cohesion, adhesion, and transpiration
cohesion, hybridization, and transpiration
Some insects can stand on the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?
The insects are light enough so they do not break the hydrogen bonds holding the water molecules together
The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
Which of the following does not result from hydrogen bonding in water molecules?
Cohesion
Adhesion
Surface Tension
Dissolving fats
Why is water considered polar?
Nonpolar covalent bonds in structure
Ionic bonds in structure
Polar covalent bonds in structure
Hydrophobic interaction in structure
Describes the breaking of a bond within a polymer using water.
Hydrolysis
Dehydration
Water is a universal solvent because it...
It can be found anywhere
It freezes when it gets cold
floats when frozen
Dissolves most substances
A water molecule has the chemical formula H2O. This means that the water molecule is made up of
Two hydrogen atoms and one oxygen atom

Why is water so good at dissolving so many substances?
it is polar
it is less dense as a solid
cohesion
adhesion
Which property of water allows it to move against gravity in plant stems?
Cohesion
Adhesion
