A temperature of -10 degrees Celsius is considered very cold. At this temperature, water freezes, turning into ice. It can cause frostbite on exposed skin in a short amount of time, so it's important to dress warmly when outside. In many regions, such as parts of Canada and Scandinavia, temperatures can drop to -10°C during winter months. This cold weather can affect daily activities, making it necessary to use heaters and wear insulated clothing to stay comfortable and safe.
