Properties Of Water Flashcards
What is a polar molecule?
Uneven distribution of electrons (form an angle)
What is water?
Chemical compound
What is cohesion?
Same molecules attracted to each other (due to h bonding)
What is surface tension? (Cohesion)
Group of water molecules at the surface of a body of water
What is adhesion?
Different kinds of molecules are attracted to each other
How does water get to the top of a tree?
Transpiration is built on cohesion and adhesion
What is a solvent?
Solvents dissolve solutes creating aqueous solutions
What is hydrophilic?
Water loving; attracted to water
What is hydrophobic?
Water fearing; no attraction to water
Why does ice float?
Because water is less dense as a solid than as a liquid
Why don’t oceans and lakes freeze solid?
Because surface ice insulates water below
What is specific heat?
Due to h bonding
What is high heat of vaporization?
Energy released to transform a liquid to a gas
What is a ph scale?
The concentration of hydrogen ions
What is a buffer?
Keeps ph stable
