liquid nitrogen boils at 77 k. convert this temperature to degrees celsius

Answer 1

To convert from Kelvin to degrees Celsius, you can use the formula:

\[ °C = K - 273.15 \]

For liquid nitrogen, which boils at 77 K:

\[ °C = 77 , K - 273.15 = -196.15 , °C \]

So, liquid nitrogen boils at approximately -196.15 degrees Celsius.
