chlorine boils at 239 k. what is the boiling point of chlorine expressed in degrees celsius? a. 93°c b. 34°c c. –61°c d. –34°c

tankabanditka [31]

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

= $- 34^{0}C$

Thus, we can conclude that when chlorine boils at 239 K then boiling point of chlorine expressed in degrees Celsius is $- 34^{0}C$ .
