Question

Liquid nitrogen boils at –195.8°C. Express the boiling point of liquid nitrogen in kelvin

Answer 1

Answer:

$\boxed {\boxed {\sf 77.35 \ K}}$

Explanation:

The Celsius and Kelvin scales are used to measure the temperature of matter.  Their scales and unit differences are the same (1 K increase = 1 °C increase), but they have different starting points.

So, the conversion is quite simple and only requires addition because of the different starting points. The formula is:

$T_K = T_C+ 273.15$

The boiling point of liquid nitrogen is -195.8 °C. We can substitute this value into the formula.

$T_K= -195.8 + 273.15$

$T_K= 77.35 K$

The boiling point of liquid nitrogen is 77.35 Kelvin.
