Freezing[1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. · The universally recognized freezing point of pure water is 0°C (zero degrees Celsius) or 32°F (thirty-two degrees Fahrenheit). At this specific temperature, water transitions from its liquid state to solid ice. This phase change occurs as water molecules slow down and arrange themselves into a crystalline structure. Learn what freezingtemperature definition means in everyday life and science. Discover how to measure it accurately and understand its impact on weather, water, and daily activities. It is one of the key phase changes of matter and occurs when the temperature of the liquid reaches or drops below a specific value called the freezing point. [1-4] A common example of freezing is water turning into ice. The freezing point of water is 0°C (32°F) at standard atmospheric pressure. The most commonly recognized freezing point is that of water, which is 32°F (0°C), although water can be supercooled to temperatures as low as -55°F (-48.3°C) without freezing. The standard freezingtemperature for pure water is a universally accepted reference point in science, defined at standard atmospheric pressure (average pressure at sea level). A freeze occurs when the temperature drops below 32°F. Freezes and their effects are significant during the growing season. Frost develops on clear, calm nights and can occur when the air temperature is in the mid-30s. Each plant species has a different tolerance to cold temperatures.
