Here's why:
* Argon's boiling point: Argon has a boiling point of -185.8 degrees Celsius (-302.4 degrees Fahrenheit).
* Temperature and state of matter: Substances exist in different states of matter depending on their temperature.
* At temperatures below their boiling point, substances are typically liquids or solids.
* At temperatures above their boiling point, substances are typically gases.
Since 25 degrees Celsius is significantly higher than argon's boiling point, argon will be in its gaseous state at that temperature.
