Questions & Step-by-Step Solutions

What is the main difference between adsorption and absorption?
  • Step 1: Understand the terms 'adsorption' and 'absorption'.
  • Step 2: Know that 'adsorption' means something sticks to the surface of a material.
  • Step 3: Realize that 'absorption' means something is taken in throughout the whole material.
  • Step 4: Remember that in adsorption, only the outer layer is involved, while in absorption, the entire volume is affected.
  • Step 5: Conclude that the main difference is that adsorption is about surfaces, and absorption is about the whole material.
