Water Properties

Front

What is surface tension in water?

Back

Surface tension is the cohesive force between water molecules that causes the surface of water to behave like a stretched elastic membrane.

Front

What type of bond exists between water molecules?

Back

Hydrogen bonds.

Front

How do large bodies of water affect nearby climates?

Back

They absorb heat in the summer and slowly release that heat in the winter, moderating temperature extremes.

Front

Why do water molecules stick together?

Back

Water molecules stick together because one side has a positive charge (hydrogen) and the other side has a negative charge (oxygen), leading to polar interactions.

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction of water molecules to other substances.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules due to hydrogen bonding.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and store large amounts of heat without significant temperature changes, which is crucial for regulating climate.

Front

What role do hydrogen bonds play in water's properties?

Back

Hydrogen bonds contribute to water's unique properties, including high surface tension, high specific heat, and the ability to dissolve many substances.

Front

What is the difference between adhesion and cohesion?

Back

Adhesion is the attraction between water molecules and other substances, while cohesion is the attraction between water molecules themselves.

Front

How does water's polarity affect its interactions with other molecules?

Back

Water's polarity allows it to interact with and dissolve many ionic and polar substances, making it a universal solvent.
