Chlorine is a gas at room temperature, so it doesn't have a boiling point at room temperature.

Here's why:

* Boiling Point: The boiling point is the temperature at which a liquid changes into a gas.

* Chlorine's State: Chlorine is a gas at standard room temperature and pressure (around 20°C or 68°F).

Chlorine's Boiling Point: The boiling point of chlorine is -34.04 °C (-29.27 °F). This means that chlorine will only boil and become a gas when the temperature is below this point.
