-12 degrees Celsius is a temperature that is below the freezing point of water, which is 0 degrees Celsius. At this temperature, water turns into ice, and snow can form in the atmosphere. It is commonly experienced in winter months in many regions, especially in places with cold climates. At -12 degrees, outdoor activities may become challenging due to the cold. People need to wear appropriate clothing, such as insulated jackets and gloves, to stay warm. This temperature can also affect vehicles, as batteries may struggle to function efficiently in such cold conditions.
