T5 Lesson 1 Properties of Water - Amoeba Sisters

What property of water allows individual water molecules to easily bond with other water molecules?

• High specific heat

• Polarity

• Low density

• Evaporative cooling

How do water molecules move upwards through the xylem in plants, defying gravity?

• Water molecules stick to each other (cohesion) and to the xylem walls (adhesion).

• Water molecules are pushed up by the roots.

• Water molecules are pulled up by the leaves through osmosis.

• Water molecules become less dense and float upwards.

Why is it beneficial for aquatic life that ice floats on water?

• Floating ice increases the amount of oxygen in the water.

• Floating ice allows aquatic animals to walk on the surface.

• Floating ice creates an insulating layer, preventing the entire body of water from freezing.

• Floating ice makes the water colder, which aquatic life prefers.

What property of water helps stabilize the temperature of aquatic environments and organisms?

• Its ability to act as a super solvent.

• Its high specific heat.

• Its cohesive properties.

• Its evaporative cooling effect.
