The boiling point of liquid nitrogen is:

Correct option is C

Correct Answer: (C) -196 °C

Explanation:
The boiling point of liquid nitrogen is -196°C (77 K or -320°F) at standard atmospheric pressure. This means that at this temperature, liquid nitrogen changes from a liquid to a gas.

Information Booster:
Liquid nitrogen is commonly used as a coolant in laboratories and medical applications.
Due to its extremely low temperature, it can cause instant frostbite upon contact with skin.

Additional Knowledge:
Liquid nitrogen (LN2) boils at -196°C and is used for cryopreservation, cryotherapy, and food freezing.
Stored in Dewar flasks to prevent rapid evaporation.
Creates a fog effect when exposed to air due to moisture condensation.
Used in science, medicine, and industry.
Can cause frostbite or cold burns if mishandled.
