On the #"absolute temperatre scale"#, #0# #"Kelvin"# #=# #-273.15# #""^@C#.

Explanation:

And thus #20*K# #=# #-253.15# #""^@C#, the normal boiling point of dihydrogen gas.

Typically, in the laboratory we use liquid nitrogen, #"b.p. = "-196# #""^@C#, as a coolant. If we were use to argon gas in our reactions, #"b.p. = "-185.9# #""^@C#, could there be any potential problem in its use?
