Answer 1

Answer:

hey mate here is ur answer

boiling point of nitrogen at °C is -196°c

to change this boiling point into kelvin we should add 273 into it...

therefore kelvin = -196+273

=77K

hope it helps u cutie

Answer 2

Concept: Temperature is a measurement of the hotness or coldness of a body. The scales of measurement of temperature are as follows:

Celsius, Fahrenheit, and Kelvin scale.

Given: Liquid nitrogen boils at -196°c.

Find: Temperature in kelvin scale.

Explanation: According to the Kelvin scale, $1K = 273$°$c.$

                     So, the kelvin temperature.          

                                                                  $= -196+273\\= 77k.$

Hence, the answer is $77k.$
