Final answer:

Liquid nitrogen does not change from a liquid to a gas without the help of a burner. It needs to be exposed to a lower temperature than its boiling point to turn into a gas.

Step-by-step explanation:

False. Liquid nitrogen can change from a liquid to a gas without the help of a burner because of its low boiling point, not because of the energy in the room. Liquid nitrogen boils at a temperature of 77 K (-196°C) at atmospheric pressure. This means that at room temperature, the energy in the room is not sufficient to boil liquid nitrogen.


To change liquid nitrogen into a gas, it needs to be exposed to a lower temperature than its boiling point, such as being placed in a cryogenic container or being poured onto a surface or object that is at a lower temperature than its boiling point.
