According to the Kinetic Molecular Theory a liquid's (SELECT ALL THAT APPLY)
particles are held close together by intermolecular forces
particles are in constant motion
particles are vibrating in place and closely packed
particles are not moving
The properties of liquids include (SELECT ALL THAT APPLY)
definite volume
take the shape of the container
can flow
are relatively incompressible
can diffuse and have surfacre tension
A meniscus forms from a liquid in a test tube due to
capillary action
surface tension
evaporation
diffusion
Why is water a polar molecule? (SELECT ALL THAT APPLY)
becaus of the bent shape of a water molecule
because of the large electronegativity difference betweeen oxygen and hydrogen.
because of the linear shape of a water molecule
due to hydrogen bonding
What is responisble for water's unique properties such as high boiling point, high heat (enthalpy) of fusion and high heat (enthalpy) of vaporization?
water's structure allows for hydrogen bonding
ionic bonding
it's ability to ionize
it's linear shape
Is more energy required melt or to boil the same amount of water?
Boiling requires more energy
melting requires more energy
it takes the same amount of energy to melt water or to boil water
Surface tension is the property of water in which...
water molecules at the surface tend to stick together.
water spills easily.
water tends to be see-through.
water tends to push up into a dome over a container before it finally spills.
Water is "sticky" because...
of cohesion.
of adhesion.
of the attraction between the positively charged hydrogen atoms and the negatively charged oxygen atom.
of capillary action.
Why does ice float on liquid water?
Ice does not float on liquid water.
It has a higher density than liquid water.
It floats because it has lower density than liquid water.
adhesion and cohesion
The ability of water to move upward, against gravity, through small openings.
specific heat index
