What is cohesion in water molecules?
Cohesion refers to the hydrogen bonds holding water molecules together.
How does surface tension benefit organisms like water striders?
Surface tension allows organisms like water striders to walk on water without sinking.
What causes water molecules to adhere to other substances?
The polarity of water causes it to be attracted to other polar molecules, a property known as adhesion.
What is capillary action and what causes it?
Capillary action is the movement of water within narrow spaces due to adhesion and cohesion, overcoming gravity.
Why do substances with polar molecules get wet in water?
Polar molecules form hydrogen bonds with water, leading to adhesion and wetting.
What is the significance of water's high heat of vaporization?
It allows water to absorb a lot of heat before evaporating, which helps cool body surfaces through evaporation.
