SC.912.L.18.12 - Properties of water

A(n) ______ is a substance with a pH less than 7

• Acid
• Alkaline
• Base
• Buffer

This is the quality that allows water gliders to walk on water

• specific heat
• capillarity
• surface tension
• super solvent

Which is NOT a unique property of water?

• Frozen water floats on liquid water.
• Water covers most of the Earth’s surface and retains a large amount of heat.
• Water molecules stick to each other through hydrogen bonds.
• Water cools very rapidly.

The normal pH scale goes from

• 0 - 12
• 0 - 14
• 0 - 7
• 0 - 10

A(n) _______ is a substance with a pH greater than 7.

• Base
• Acid
• Buffer
• Water

Large bodies of water do not quickly fluctuate in temperature. Why?

• Water is a solvent.
• Water has a high heat capacity.
• Water acts as a buffer.
• Water is non-polar.

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Capillary action pulls the water molecules like a chain
• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves

The process by which a liquid changes to a gas when heat is added.

• evaporation
• condensation
• precipitation
• melting point

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Large bodies of water do not quickly fluctuate in temperature. Why?

• Water is a solvent.
• Water has a high heat capacity.
• Water acts as a buffer.
• Water is non-polar.
