Can You Freeze Liquid Nitrogen?

Yes, you can freeze liquid nitrogen at -210°C (-346°F), but it requires specialized equipment that reaches much lower temperatures than standard storage systems. Your dewars, tanks, and freezers maintain liquid nitrogen around -196°C (-321°F), which keeps it in liquid form during normal operations. Below, you will learn: WestAir supplies nitrogen across California and Arizona. Why Would You …

What Happens If You MIG Weld Without Gas?

MIG welding without gas causes poor weld quality due to oxidation and contamination. The absence of shielding gas allows air to reach the weld, creating porosity, weak joints, and excessive spatter. Flux-cored wire is the primary substitute for shielding gas. It offers a viable gasless alternative by generating its own protective shielding. In this guide, …

What Is a Noble Gas?

A noble gas is a chemically inert element found in Group 18 of the periodic table. Noble gases include helium, neon, argon, krypton, xenon, and radon. These gases have full outer electron shells, which make them highly stable and unlikely to form chemical bonds under normal conditions. In this guide, we’ll explore the fundamental properties …

Is Krypton Rare?

Krypton is one of the rarest gases on Earth, present in our atmosphere at only about 1 part per million (ppm). This scarcity makes it significantly more challenging and expensive to extract compared to other industrial gases. In this guide, we’ll explore why krypton is so rare. You’ll also learn how its limited availability affects …

How Cold is Liquid CO₂?

The temperature range of liquid CO₂ is  between -56.6°C and 31.1°C, but only under specific pressure conditions above 5.11 atmospheres. Unlike water, which remains liquid at atmospheric pressure across a wide temperature spectrum, liquid carbon dioxide requires carefully controlled pressure and temperature to prevent it from turning into solid dry ice or gas. In this …

How Cold Is Dry Ice?

Dry ice reaches an extreme temperature of -78.5°C (-109.3°F) as it sublimates under standard atmospheric pressure. This temperature can drop even lower under certain conditions, which makes dry ice one of the coldest materials commonly used in industrial applications. In this guide, we’ll explore the temperature properties of dry ice, as well as: WestAir supplies dry …
