This category is for images that are connected with cooling with gases. Food, biological tissue, and items undergoing heat stress cycling are often cooled using gases. Sometimes the gas is employed in liquid form, The most popular being liquid nitrogen. Sometime the gas CO₂ is in the solid form of dry ice. Sometime the sudden expansion of compressed gas is used for cooling. In alphabetical order:

Category:Argon used for cooling. Example: Aluminum production.

Category:Carbon dioxide (gaseous) used for cooling. Examples: Early refrigeration. Heat stress cycling.
