Question

Dermatologists often remove small precancerous skin lesions by freezing them quickly with liquid nitrogen, which has a temperature of 77 K. What is this temperature on the (a) What is this temperature on the Celsius scale? ° C (b) What is this temperature on the Fahrenheit scale?

Answer 1

a)-196°C

b)-320.8° F

Step-by-step explanation:

Given the temperature in Kelvin As 77K

a) temperature in Kelvin= temp. in Celsius+273

So temperature in degree Celsius= 77-273= -196°C

b) Temperature in Farenheit

`F= ((9C)/(5)+32)`

`F= ((9*(-196))/(5)+32)`

=-320.8° F
