Left Side: 1 Liter of Liquid Nitrogen (LN₂) A small, transparent container labeled “1L LN₂” at −196°C. Placed next to a standard soda can for scale. Right Side: 700 Liters of Nitrogen Gas (N₂) A large, transparent balloon or tank labeled “700L N₂ Gas” at room temperature. The gas expands dramatically, filling the space. LEAP Engine for Scale The LEAP engine (used in aircraft like the Airbus A320neo and Boeing 737 MAX) is shown in the background. The engine is ~2.1 meters in diameter and 3.3 meters long, providing a sense of scale for the gas expansion. Mehr sehen
