A room loses heat; an angry person becomes calmer. Cool down can describe either change. The soup examples show someone actively making another thing cooler.
The idea
Use cool down without an object for becoming cooler or less angry. To make something cooler, say cool down the soup / cool the soup down, but cool it down. The past is cooled; cold is an adjective.
Examples
- The kitchen cooled down after sunset.
- Mina cooled the soup down with a little cold water.
- Mina cooled down the soup with a little cold water.
- It is still too hot; let it cool down.
- Omar needed a few minutes to cool down after the argument.
- A short walk helped Lea cool down after the disagreement.

Watch out
Cooling down does not mean becoming freezing cold; it means losing heat. In an argument, it can mean losing anger. Telling someone Cool down! directly may sound dismissive, so consider the situation.
