Question 1

Which property of water makes it helpful to use in car radiators?

"Your engine's radiator is one of the most important parts of your cooling system. Your engine's temperature is constantly watched by a special thermostat. When the engine gets too hot, the thermostat releases engine coolant, or antifreeze, from your radiator into your engine."

Water can climb up the sides of a tube.

Water has a high heat of vaporization.

Water is a universal solvent.

Water is more dense than the motor oil in the engine.

Question 2

Between the hydrogen atoms of two water molecules.

Between the hydrogen atom of one water molecule and the oxygen atom of another.

Between the oxygen atoms of two water molecules.

Molecules of water do not form hydrogen bonds.

Question 3

The density of the water molecule helps it to be cohesive with nearby water molecules, forming a skin over it.

The polarity of the water molecule helps it to be cohesive with nearby water molecules, forming a skin over it.

The weight of the water molecule helps it to be cohesive with nearby water molecules, forming a skin over it.

The buffering ability of the water molecule helps it to be cohesive with nearby water molecules forming a skin over it.

Question 4

Flooding would occur and animals would be forced to migrate

Harmful organisms living in water would reproduce at a rapid rate

Organisms that are sensitive to changes in temperature would die

Plants would not have enough water to effectively carry out photosynthesis

Question 5

As the water cooled, it adhered to the can, causing it to split

When the water froze, the space between the water molecules expanded due to hydrogen bonds

When the water froze, it weakened the molecular bonds in the aluminum can

As the water cooled, the surface tension of the water decreased and the can collapsed
