Answer: Option (d) is the correct answer.
Explanation:
It is given that boiling point of chlorine is 239 K. To convert temperature in degree Celsius, use the formula as follows.
Temperature in Kelvin = Temperature in degree Celsius + 273
or, Temperature in degree Celsius = Temperature in Kelvin - 273
= 239 - 273
= [tex]- 34^{0}C[/tex]
Thus, we can conclude that when chlorine boils at 239 K then boiling point of chlorine expressed in degrees Celsius is [tex]- 34^{0}C[/tex].
