Properties of Water

When water molecules stick easily to other water molecules, this is called what?

• cohesion
• adhesion
• solution
• polar molecule

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

Water molecules are attracted to other kinds of molecules because of the property.

• Cohesion
• Adhesion
• Surface Tension
• Universal Solvent

Which statement best describes an effect of the low density of frozen water on a lake?

• When water freezes it contracts, decreasing the water level in the lake.
• Water in a lake freezes from the bottom up
• Water removes thermal energy from the land, causing the lake to freeze
• When water in a lake freezes, it floats and provides insulation for the organisms below

Water is cohesive, the molecules are attracted to one another because of hydrogen bonds. This attraction helps create...

• surface action
• surface tension
• ice
• solvents

When water travels up the stem of a plant, this is a result of

• surface tension
• capillary action and adhesion
• capillary action and cohesion
• cohesion and adhesion

What property of water is being shown?

• specific heat
• surface tension
• polarity
• solution

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.

Which term refers to water having partial positive and a partial negative charge?

• cohesion
• surface tension
• polarity
• adhesion

A high specific heat means...

• It heats up quickly with energy added
• It requires more energy to change temperature
