1. Please list the five different surfaces when the three phases (solid, liquid and gas) contact each other?

2. Please list the four metastable state in thermodynamics?

3. True or false?

The higher of the degree of dispersion makes the surface area bigger, and the surface effect is more obvious.

4. True or false?

a. Chemical adsorption is reversible

b. Physical adsorption is a single-layer adsorption

c. The adsorption force for Physical adsorption is VDW (Van der Waals' force)
