Question

Liquid nitrogen has a boiling point of −195.81°C at atmospheric pressure. Express this temperature (b) in kelvis

Answer 1

The boiling point of liquid nitrogen, which is -195.81°C, can be converted to Kelvin by adding 273.15. This gives us 77.34 Kelvin.

Step-by-step explanation:

The boiling point of liquid nitrogen is stated as -195.81°C. However, the question asks for this temperature to be converted to Kelvin. It is important to note that the Kelvin scale starts at absolute zero, which is equivalent to -273.15°C. Therefore, to convert Celsius to Kelvin, you simply add 273.15 to the Celsius temperature.

For liquid nitrogen: -195.81°C + 273.15 = 77.34 K

So, the boiling point of liquid nitrogen is 77.34 Kelvin (K) at atmospheric pressure.
