Absorption describes the process of absorbing or soaking up something: Sponges are good at water absorption; dark colors are better for heat absorption.

Because the words absorption and absorb are so closely related, there's a tendency for people to try to spell absorption with a second B instead of a P, but don't fall for it. Remembering the correct spelling is going to take total absorption in studying — meaning you'll have to be totally focused and occupied with learning it.
