Properties of Water
This property causes water to "stick" to other substances or things.
What is adhesion?
What is the chemical formula for water?
What is H20?
This type of bond holds separate water molecules together.
What is a hydrogen bond?
What property causes ice to float in water?
What is low density as a solid?
This is an attraction between like molecules (e.g.: Water molecules are attracted to other water molecules).
What is cohesion?
A substance that does NOT dissolve in water and is "water-fearing"
Non-polar and/or hydrophobic
This type of bond forms when electrons are shared between two or more atoms.
What is a covalent bond.
This is an attraction between unlike molecules.
What is adhesion?
This property of water means that it takes a large amount of heat energy to raise the temperature of water.
What is high heat capacity or specific heat?
What kind of charge does water have?
What is partially positive and partially negative?
These subatomic particles determine the chemical properties of an atom/element and have a negative charge.
What are electrons?
This property of water causes the beach water to be cold in May 80 degree weather.
What is high heat capacity or specific heat?
This property of water allows a substance like pepper to "sit" on top of water.
What is surface tension?
What causes polarity in a water molecule?
What is the unequal sharing of electrons between the hydrogens and oxygen?
This type of bond forms when a Na+ ion and Cl- ion to form NaCL.
What is an ionic bond?
This property of water allows it to dissolve many solutes, and is why water is known as the "universal solvent".
What is polarity? (water will dissolve ionic compounds and other polar molecules).
What property causes water to travel from the root systems of trees all the way to the top branches?
What is capillary action?
What two properties combined, cause capillary action?
cohesion and adhesion
The bonds between an oxygen and one two hydrogens WITHIN a water molecule.
What are covalent bonds?
Give one examples of how water is important for homeostasis.
Answers will vary.
