Adsorption: This is when molecules stick onto a surface - just like how some songs 'stick' with our concert-goers more than others.
Partition Coefficient: This measures how much a compound prefers to be in one phase over another - similar to how some fans might prefer slower ballads over fast-paced rock tunes.
Retention Time: The time it takes for a particular compound to pass through the system under set conditions - akin to how long each song plays during the concert.
