Properties of Water, pH scale, and Composition of matter

Water is attracted to itself, which is known as

• adhesion

• cohesion

• heat of vaporization

• Thermal Buffer

Refer to the picture; the water strider can walk over waters surface. This is occurring due to:

• Adhesion

• Cohesion

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.
