Water climbing up a paper towel
Water molecules attracting each other
How does cohesion contribute to the surface tension of water?
By allowing water to stick to other surfaces
By causing water molecules to repel each other
By creating a strong bond between water molecules
By reducing the density of water
Which experiment would best demonstrate adhesion?
Dropping water on a waxed surface

What role does adhesion play in the process of transpiration in plants?
It helps water molecules stick to each other
It allows water to move through the plant's xylem
It prevents water loss from the leaves
It increases the rate of photosynthesis
Why do water droplets form on the outside of a cold glass?
Due to cohesion between water molecules
Due to adhesion between water molecules and the glass surface
Due to the condensation of water vapor
Due to the evaporation of water
