Water

Question 1

Water

Answer 1

made up of three atoms: two hydrogen and one oxygen

Question 2

Water Molecule

Answer 2

H2O

Question 3

Oxygen Atom

Answer 3

attracts electrons; negative charge; one in a water molecule

Question 4

Hydrogen Atom

Answer 4

positive charge; two in a water molecule

Question 5

Hydrogen Bonds

Answer 5

formed between two different water molecules; positive hydrogen end, negative oxygen end

Question 6

Interaction between Water Molecules

Answer 6

hydrogen bond end of one water molecule; molecule is attracted to positive end of another water molecule

Question 7

Cohesion

Answer 7

attraction between water particles of the same substance; results in surface tension; produces a surface film
ex) water striders

Question 8

Adhesion

Answer 8

attraction between two different substances; water will make hydrogen bonds with other surfaces
ex) transpiration

Question 9

High Specific Heat

Answer 9

amount of heat needed to raise or lower 1g of a substance by 1C degree; water resists temp change, both heating and cooling; water can absorb or release large amounts heat energy with literal in actual temp

Question 10

Water Density as a Solid

Answer 10

water is less dense as a solid; ice is less dense than a liquid, ice floats; frozen water forms crystal like lattice

Question 11

Solute

Answer 11

substance that is being dissolved

Question 12

Solvent

Answer 12

substance into which the solute dissolves
