It is in the gaseous state. The boiling point of chlorine is -34.4 degrees Celsius, therefore at room temperature of about 20-23.5 degrees Celsius, it is a gas. "Chlorine" is sometimes used colloquially to refer to compounds containing chlorine (or even, confusingly, compounds which do NOT actually contain chlorine), particularly those used as disinfectants in Swimming Pools. These might be solids, liquids, or solutions, depending on exactly what the compound is.
Gas.
At standard temperature and pressure, chlorine will be a gas.
Depends on the temperature and pressure. At room temp and pressure, chlorine is a gas.
the answer is gas
Chlorine is a pale green gas at room temperature.
At room temperature: Chlorine: gas Helium: gas Hydrogen: gas Oxygen: gas
Chlorine is a gas at room temperture.
At room temperature and standard pressure the element Chlorine is a gas.
At room temperature sodium is a solid and chlorine is a gas.
At standard temperature and pressure, chlorine will be a gas.
Depends on the temperature and pressure. At room temp and pressure, chlorine is a gas.
A gas
the answer is gas
Chlorine is a gas at room temperature and pressure, not a solid.
Chlorine gas (Cl2) is in the gaseous state at room temperature and pressure.
Chlorine is typically found in its gaseous state at room temperature and pressure.
it is a gas at room temperature(don't listen to this answer it is very wrong, actually chlorine is liquid at room temperature) It is a (light green) gas and very toxic
Room temperature is room remperature. Chlorine has nothing to do with it.
