Properties of Water: Cohesion and Adhesion

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances, causing water to stick to surfaces like leaves.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules, which allows them to stick together.

Front

What is a polar molecule?

Back

A polar molecule is a molecule in which opposite ends have opposite electric charges, like water (H2O).

Front

What are hydrogen bonds?

Back

Hydrogen bonds are attractions between water molecules that occur due to the polarity of water.

Front

What is the term for water's ability to climb upwards against the force of gravity?

Back

Capillary action.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

Front

How does temperature affect the properties of water?

Back

As temperature increases, water molecules move faster, reducing cohesion and adhesion, which can affect processes like evaporation.

Front

What role does water's polarity play in its solvent abilities?

Back

Water's polarity allows it to dissolve many substances, making it an excellent solvent.

Front

What is an example of adhesion in nature?

Back

Water droplets sticking to the surface of a leaf is an example of adhesion.

Front

What is an example of cohesion in nature?

Back

Water forming droplets on a surface due to cohesion is an example.
