Azotul are o temperatură de -195,8 grade Celsius. În mod normal este utilizat pentru congelarea verucilor sau pentru crioconservare. Youtuber-ul Grand Theompson s-a întrebat ce se va întâmpla dacă toarnă azot într-un balon.
Probabil că majoritatea persoanelor s-ar aştepta ca balonul să îngheţe şi să crape din cauza temperaturii scăzute, rezultatul este mult mai interesant. După cum se poate observa şi în videoclipul următor, balonul începe să se umfle. Acest fenomen se produce deoarece punctul de fierbere al nitrogenului lichid este de -195,8 grade Celsius, ceea ce înseamnă că se transformă foarte repede dinsubstanţă lichidă în substanţă gazoasă atunci când aceasta atinge temperatura Pământului.
