Front

What two elements make up water?

Back

Hydrogen and oxygen.

Front

Describe COHESION.

Back

Water molecules attracted to other water molecules.

Front

What is adhesion?

Back

Water's ability to stick to other substances.

Front

Water's ability to stick to glass is called what?

Back

Adhesion.

Front

What is surface tension?

Back

The cohesive force between liquid molecules at the surface that makes it behave like a stretched elastic membrane.

Front

What is an example of cohesion in water?

Back

Water droplets forming on a surface.

Front

What is an example of adhesion in water?

Back

Water molecules sticking to a leaf.

Front

What is capillary action?

Back

The ability of water to flow in narrow spaces without the assistance of external forces.

Front

How does temperature affect surface tension?

Back

Higher temperatures generally decrease surface tension.

Front

What role does cohesion play in water transport in plants?

Back

Cohesion helps water molecules stick together, allowing them to move up through plant stems.
