Properties of Water

Front

What is the reason water is considered a universal solvent?

Back

Water dissolves most substances due to its polar nature.

Front

What does the term 'adhesive' mean in the context of water?

Back

Adhesive refers to the property of water molecules sticking to other surfaces.

Front

What is capillary action?

Back

Capillary action is the ability of water to move through small spaces, such as plant roots and porous materials.

Front

Which part of the water molecule has a slightly negative charge?

Back

The oxygen end of the water molecule has a slightly negative charge.

Front

What is surface tension in relation to water?

Back

Surface tension is the cohesive force that allows water to resist external force, enabling phenomena like water droplets bouncing.

Front

How does the polarity of water contribute to its properties?

Back

The polarity of water molecules leads to hydrogen bonding, which is responsible for many of water's unique properties.

Front

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

Back

Water's high specific heat allows it to absorb and retain heat, moderating temperature changes in the environment.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, which is why ice floats on liquid water.

Front

What role does water play in biological systems?

Back

Water is essential for life, serving as a solvent, a medium for chemical reactions, and a means of temperature regulation.

Front

What is the difference between cohesion and adhesion in water?

Back

Cohesion refers to water molecules sticking to each other, while adhesion refers to water molecules sticking to other surfaces.
