Temperature went down

Answer:

Temperature.

Explanation:

The gas particles movements directly depend on temperature.

Is temperature is changed, particles react to it. High temperature means high movement speed. Low temperature means low movement speed.

So, in this case, temperature falling down explains best this phenomenon.
