Premise[]
Simple calc for the Ring of Winter relic owned by Artus Climber. Basically, the ring can manipulate the heat of a short-ranged area down to -30 F, or -34.44 C.
Calc[]
So the sphere it affects has a radius of 120 ft, or 36.576 meters. A sphere with such a radius would have a volume of 2.05e5 m^3.
Density of Air = 1.225 kg/m^3
Mass = 251125 kg
Now we need specific heat. It's like 6 AM so gonna use this.
Temp Change = 50.44 C
Specific Heat of Air = 1012 J/(kg*K)
Plugging in our values we get 1.282e10 Joules, Large Building level but lower than what he scales to. It states it can create frostbite on anything in the locale but what that actually constitutes is questionable.
Oh well. Nice supporting feat for High 8-C I guess.
