Subzero

Subzero refers to temperatures below zero degrees Celsius (32 degrees Fahrenheit), where water freezes and many environmental processes change. It is commonly used to describe extremely cold weather conditions, especially in regions experiencing winter. Subzero temperatures can impact daily life, affecting travel, infrastructure, and personal safety. In scientific terms, it indicates a state in which gases can condense, and solids may become brittle. It is also relevant in various fields, such as meteorology and engineering, where material behavior at low temperatures must be considered. Subzero conditions can pose risks like frostbite and hypothermia for unprotected individuals.
