The Properties of Water

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes.
• Capillary action pulls the water molecules like a chain.
• Water is pulled by gravity.
• Water’s cohesion causes it to “pull” towards the leaves.

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides
