The type of bond that exists between the oxygen and hydrogen within a water molecule
hydrogen bond
covalent bond
ionic bond
nonpolar bond
Due to unequal sharing of electrons, water is a ____________ molecule.
polar
nonpolar
ionic
hydrogen
Water has a ___________ charge near the oxygen atom.
negative
positive
partial positive
partial negative
Water has a ______________ charge near the hydrogen atom.
positive
negative
partial positive
partial negative
A relatively weak bond between the partial negative side of one molecule and the partial positive side of another molecule
covalent bond
ionic gond
hydrogen bond
One water molecule is attracted to another water molecule
adhesion
cohesion
capillary action
high heat capacity
Water molecule is attracted to something other than water
adhesion
cohesion
capillary action
high heat capacity
The property of cohesion is due to water's ability to form
covalent bonds
hydrogen bonds
nonpolar bonds
ionic bonds
allows insects such as water striders to be able to walk across the surface of water
adhesion
surface tension
capillary action
transpiration
the ability of water to flow in narrow spaces without the assistance of and in opposition to gravitational forces
cohesion
adhesion
capillary action
high heat capacity
Adhesion is due to ___________ bonding
covalent
ionic
hydrogen
The amount of energy needed to raise 1 gram of water 1 degree celsius
cohesion
boiling temperature
specific heat
adhesion
Water has a high specific heat and boiling point because the energy of heat is absorbed in an attempt to break ________________ bonds.
covalent
nonpolar
hydrogen
ionic
The ability of water to absorb a tremendous amount of heat energy without increasing in temperature is important for life because
it keeps the Earth cool enough to sustain life
it regulates human body temperature
both options
Water has a higher density as a liquid than as a solid; therefore ice floats. This is because
when water freezes the hydrogen bonds are no longer breaking and reforming and are frozen at the greatest distance away from each other
when water freezes hydrogen bonds have the greatest amount of energy and are constantly moving
when water freezes hydrogen bonds are frozen in a lattice at the closest distance possible to each other
Because water is ________________, it is the greatest solvent on Earth
nonpolar
polar
hydrophobic
slightly positive
oils, fats, waxes
examples of polar molecules
examples of nonpolar molecules
examples of salts
examples of hydrophilic substances
A neutral pH is one of the value
below 7
above 7
7
In water, the electrons are not shared equally creating a _________ molecule
large
weak
polar
nonpolar
Water is called the _______________ solvent.
weakest
universal
solute
adhesive
