What does it mean when water molecules are described as 'cohesive'?

• Water molecules are attracted to (stick to) other water molecules. This explains water’s spherical drop shape.

• Water molecules are repelled by other water molecules, causing them to spread apart.

• Water molecules are attracted to oil molecules, allowing them to mix easily.

• Water molecules evaporate quickly due to weak intermolecular forces.

Which property of water explains why water droplets are spherical in shape?

• Adhesion

• Cohesion

• Evaporation

• Condensation

What is surface tension?

• The ability of water to evaporate quickly

• The top layer of water molecules are extra cohesive and create a skin-like surface

• The process of water freezing

• The movement of water underground

Fill in the blank: The top layer of water molecules are extra ______ and create a skin-like surface.

• cohesive

• fragile

• repellent

• adhesive

The image shows an insect standing on water. This is an example of which property of water?

• Surface tension

• Boiling point

• Freezing point

• Density

What does the adhesive property of water allow it to do in plants?

• Stick to other water molecules only

• Stick to other molecules and climb against gravity to bring water to a plant

• Prevent water from moving up the plant

• Only move water downwards
