F34: Surface Tension

 

Purpose: To exhibit surface tension and capillarity effects.

Description:

 

Cenco-Miller Surface Tension Demonstrator, colored water, mercury or other liquid in which cohesive forces between liquid molecules are greater than adhesive forces between liquid and glass molecules.

Pour water into one side and mercury into the other side of the demonstrator. Display the shape of the liquid surface in the sharp corners of the wedge-shaped sides. The water curves upward near the point and the mercury curves downward.

Equipment List: Storage Location: CHEMP 130A
