Adsorbed

ADSORBED A008

This means to take up and cause to adhere in a thin film on the surface of a solid.

Moisture is adsorbed on to the carbon graphite combination we use for a mechanical seal face, allowing the graphite to release as a lubricating film.

This same action takes place when we wet the tip of a graphite pencil to make the writing on the paper darker and easier to read.
