The state of liquid nitrogen after boiling will be a gas known as nitrogen gas (N2). When liquid nitrogen is heated, it goes through a phase transition from a liquid state to a gaseous state. During this process, the liquid nitrogen absorbs energy from the surroundings and converts into nitrogen gas. The boiling point of liquid nitrogen at atmospheric pressure is -195.8°C (-320.4°F). When the liquid nitrogen reaches this temperature and is supplied with enough heat energy, it starts to boil and converts into nitrogen gas. The nitrogen gas thus formed will occupy a much larger volume compared to the original liquid nitrogen, expanding approximately 694 times in volume.
