It depends on other properties of chlorine, such as pressure, volume, number of moles etc. Chlorine does not have one temperature in general. It is related to other physical properties. This question does not have an answer. Please specify other factors relating to chlorine's physical state...
Chlorine, itself, is a gas. Most people think it's a liquid because of the chlorine that you would put in a swimming pool. But that is chlorine mixed with other chemicals.
When gaseous hydrogen and gaseous chlorine are mixed each other, they react vigorously to form hydrogen chloride (HCl). The only way to separate elements from the gas HCl is electrolysis where chlorine is discharged at cathode and the other at anode.
Chloromethane is the product that is formed when methane and chlorine react with each other. Dichloromethane is another product that can also be formed when methane and chlorine react.

chlorine gas was one
There is no other substance in chlorine except chlorine, which is an elementary substance.
Anything that is not a noble gas will combine with chlorine.
Halogens: fluorine, chlorine, iodine, bromine, astatine, ununseptium
Chlorine elementally? No - that would almost be a contradiction of the nature of chlorine. But chlorine in combination with other elements (chlorine compounds of various types) are implicated in many kinds of cancers.
No. It's the other way around: chlorine is one of two elements in salt. The other element is sodium.
Chlorine reacts violently with a large number of elements.
With the names of the others halogens, for ex.: fluorine, iodine, bromine, chlorine.
Halogens: fluorine, chlorine, iodine, bromine, astatine, ununseptium
Chlorine is not nutrient we need in our body, like other vitamins. Chlorine is needed to keep diseases out of water.
