Properties of Water

Front

What is surface tension in water?

Back

Surface tension is the cohesive force between liquid molecules at the surface of a liquid, which allows it to resist external force.

Front

How does surface tension allow water to bounce on water?

Back

Water can bounce on water due to surface tension, which creates a 'skin' on the surface that can support small objects.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, crucial for water transport in plants.

Front

Why is capillary action important for plants?

Back

Capillary action is key for water moving from roots to leaves in plants, allowing them to obtain necessary moisture.

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances, which allows water to spread on surfaces.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules themselves, which leads to phenomena like water droplets forming a spherical shape.

Front

What percentage of Earth's water is potable?

Back

.003% of Earth's water is potable, meaning it is safe for drinking.

Front

How do water droplets maintain a spherical shape?

Back

Water droplets take a spherical shape due to cohesion, as water molecules are attracted to each other.

Front

What role does temperature play in the properties of water?

Back

Temperature affects the density, viscosity, and surface tension of water, influencing its behavior in different states.

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, moderating climate and supporting life.
