Which of the following is not a property of water?
Hydrogen bonds exist only in the solid state.
It can dissolve ionic and polar molecules.
It has a high surface tension.
The solid state is less dense than the liquid state.
Water’s unique properties arise because of its ability to form strong:
covalen bonds
hydrogen bonds
dipole bonds
ionic bonds
Ice floats on water because:
liquid water is less dense than ice
water's surface tension is strong enough to support the ice
there is oxygen dissolved in liquid water
the molecules in ice are farther apart than the molecules in liquid water
A property of water that is vital to supporting life is that:
water is transparent
water can dissolve a wide variety of substances
water is found naturally on Earth as a liquid, solid, and gas
water molecules are not charged
Cohesion is:
exemplified by the action of water droplets sticking to your drinking glass
a property that allows water to dissolve certain substances
a phenomenon that occurs only at the surface of water
an attraction between molecules of the same kind
Delle Colombe’s ebony disk did not sink in water because:
Water molecules on the surface of water form strong hydrogen bonds that can withstand the distributed weight of the disk.
The disk was flat, and all flat objects will remain suspended on the surface of water.
Water droplets that form on the bottom of the disk connect to each other and support the disk.
Ebony is less dense than water.
Oxygen can dissolve in water because:
polar water molecules induce a temporary dipole in oxygen molecules
oxygen gas is made of polar molecules
water is a bipolar molecule
both water and oxygen gas are small molecules, so there is sufficient space for one to dissolve in the other
Drops of dew on a leaf owe their spherical appearance to:
cohesion
adhesion
the density of water
cohesion, adhesion, and surface tension
Capillary action of water in a tube is the result of _____ being stronger than _____.
cohesion; adhesion
adhesion; cohesion
surface tension; cohesion
cohesion; surface tension
A frozen lake in winter with fish swimming below the surface is possible because of which property of water:
cohesion
adhesion
low molecular weight
polarity
