Tension Superficial
Objectives
In this section you will learn about the behavior of a liquid, solid gas interface. In particular you will learn about the angle at which the air-solid and air liquid interfaces and its causes.
After studying these materials you are expected to:
1) Define the term contact angle in reference to liquid-gas-solid interfaces.
2) Explain the effects of adhesive and cohesive forces on the magnitude of the angle.
3) Define the term "static contact angle".
4) Define the term "dynamic contact angle".
5) Measure static constant angles.
