Water Summary

What is water often referred to due to its ability to dissolve most substances?

Universal Solvent

What is the property of water that moderates temperature effectively?

High heat capacity

What defines adhesion in water molecules?

The attraction between molecules of different substances.

Which force is responsible for the movement of water from roots to leaves in plants?

Capillary action

What happens to the density of pure water when it freezes?

It decreases.

What is primarily responsible for water's ability to form hydrogen bonds?

Its polar nature.

Which property of water allows it to form a stable thermal habitat?

High specific heat capacity.

What results from the high surface tension of water due to hydrogen bonding?

Cohesion.

What property causes water molecules to be retained in soil?

Adhesion.

Explain one consequence of water's high specific heat capacity for aquatic animals.

Stable water temperatures protect animals like the ringed seal from extreme cold.

How does hydrogen bonding affect the movement of water in xylem?

It creates an upward force facilitating water movement.

What are the two classifications of molecules based on their affinity for water?

Hydrophilic (water-loving) and Hydrophobic (water-fearing).
