A teacher placed a beaker of limonene at the front of a
classroom. At first, the students at the back of the classroom could not smell the limonene. After two minutes,
the smell of limonene had spread throughout the classroom. The air in the classroom was still and calm.
Explain this observation using the particle model of matter.
