Liquid nitrogen. Normally a gas,nitrogen turns into a liquid at temperatures below 77.4 Kelvin (-198 degrees Celsius). The vapour in the image is formed by water droplets condensing from the air due to the extremely low nitrogen temperature. This fluid is widely used in research carried out in sub-zero temperatures and for storing biological samples | |
