FLASHCARD QUESTION

Front

What phenomenon allows water to rise in a narrow tube?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, due to the adhesive and cohesive properties of water.

2.

FLASHCARD QUESTION

Front

What is a unique property of water when it freezes?

Back

Water expands when it freezes, which is unusual for most substances. This property allows ice to float on liquid water.

3.

FLASHCARD QUESTION

Front

How does increasing salinity affect the boiling point of water?

Back

Increasing salinity raises the boiling point of water due to the presence of dissolved salts, which require more energy to break the intermolecular forces.

4.

FLASHCARD QUESTION

Front

What property of water helps organisms regulate their internal temperature?

Back

High specific heat capacity allows water to absorb and release large amounts of heat with minimal temperature change, aiding in temperature regulation.

What is the pH level of pure water?

Back

The pH level of pure water is 7, which is considered neutral on the pH scale.

Define surface tension in the context of water.

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane, allowing small objects to float.

7.

FLASHCARD QUESTION

Front

What is cohesion in relation to water molecules?

Back

Cohesion is the attraction between water molecules due to hydrogen bonding, which contributes to water's high surface tension.
