Question

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

Answer 1

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 $- 34^{0}C$.

Answer 2

K = ºC + 273

239 = ºC + 273

ºC = 239 - 273

= - 34ºC
