What is the freezing point called?
32°F
noun Physical Chemistry. the temperature at which a liquid freezes: The freezing point of water is 32°F, 0°C.
What word means below freezing temperatures?
subfreezing
Definition of subfreezing : being or marked by temperature below the freezing point (as of water) subfreezing weather.
What is the freezing zone?
Typically, frost can occur when the temperature falls below 36°F, especially in rural areas. Frost becomes more widespread when the temperature falls below 32°F with some freeze possible. A hard freeze is possible when temperatures fall below 28°F.
What is freezing point Class 12?
Freezing point is the temperature at which the liquid and the solid form of the same substance are in equilibrium and have the same vapour pressure. Due to lower vapour pressure of the solution, solid form of a solution separates out at a lower temperature.
What’s above freezing mean?
From Longman Dictionary of Contemporary English above/below freezingabove or below the temperature at which water freezes It was well below freezing last night. Yet it was not really cold here; the temperature was well above freezing point.
What is under freezing?
Freezing 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.

What is the temperature of water when it freezes?
The temperature may be lower if supercooling occurs or if there are impurities present in the water which could cause freezing point depression to occur. Under certain conditions, water may remain a liquid as cold as -40 to -42°F!
Which substance has a freezing point of 0 degrees Celsius?
The most common substance, water, has a freezing point of 0 o Celsius.
What is the process of freezing a liquid called?
In most liquids, the process of freezing involves crystallization. Crystallization is the process in which a liquid turns into a crystalline solid form upon exposure to low temperatures and altering the liquid’s atomic structure to form a crystal structure.
What is the freezing point of supercooled water?
Water is known to remain in the liquid state after supercooling even at temperatures as low as – (negative) 4000 Celsius and when exposed to high-pressure conditions, supercooled water will stay in a liquid state at low temperatures of – (negative) 700 Celsius. For comparison, the freezing point of pure water in normal conditions is 00 Celsius.
