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

inessss [21]

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.

Why am i not good enough for my mom

Lisa [10]

You are good enough in general. As long as you know and feel that you are good enough within yourself, you won’t have to worry about meeting anyone else’s expectations. Maybe it’s your mom.. not you.
