What is a haiku about convection

The fluid heated

Travels away from its source

Energy moving

A haiku consists of seventeen syllables. It's consists of three lines. The first line is made up of five syllables, the second line is made up of seven syllables and the third is again made up of five syllables. It does not rhyme and the usual themes are about nature. Convection is when a heated fluid like air or liquid moves away from where it originated and a transfer of energy takes place. Above would be a haiku about convection.
