What does below zero mean in temperature?
adjective. 1Below zero on the Fahrenheit scale (–18 Celsius); very cold. 1.1Below zero on the Celsius scale; below freezing. ‘It can feel relatively warm, even in sub-zero temperatures, if the sky is clear and the sun is shining, while a higher temperature can feel relatively cool if accompanied by a biting cold wind. …
What is the lowest temperature meaning?
Minimum temperatures of an area or place is the lowest temperature at that place in a given time period. The lowest possible temperature is -273 degree Celsius, or 0 Kelvin( Kelvin is a unit of temperature)
What temperature is below zero in Celsius?
Zero kelvin (−273.15 °C) is defined as absolute zero.
What is the value of subzero temperature?
absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.
What is absolute zero define as?
absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale. temperature scales.
How do you explain absolute zero?
Absolute zero is the lowest temperature possible. At a temperature of absolute zero there is no motion and no heat. Absolute zero occurs at a temperature of 0 degrees Kelvin, or -273.15 degrees Celsius, or at -460 degrees Fahrenheit.
What is the temperature below freezing?
Water, like all types of matter, freezes at a specific temperature. The freezing point for water is 0 degrees Celsius (32 degrees Fahrenheit). When the temperature of water falls to 0 degrees Celsius and below, it begins to change to ice.
What is the absolute zero temperature?
What is the name for low temperature?
coldness; cold; frigidity; frigidness; temperature; vasoconstrictor; vasoconstrictive; pressor.
What is minimum temperature short answer?
MINIMUM TEMPERATURE: The lowest temperature recorded—diurnally, monthly, seasonally, or annually, or the lowest temperature of the entire record. Daily air temperature minima are recorded by the screen minimum thermometer.
What is subzero condition?
also subzero. adjective. Sub-zero temperatures are below 0° centigrade or, in the United States, below 0° Fahrenheit.
Is below zero Celsius or Fahrenheit?
Water freezes at +32 °F. @toandfro – subzero means “below zero.” When used by weather forecasters in the U.S., it means “below 0°F”. (It essentially means, “It’s gonna be cold; bring your mittens and a warm hat.”)
What is the definition of sub zero?
Definition of subzero 1 : registering less than zero on some scale (especially the Fahrenheit scale) subzero temperatures.
What is absolute zero and absolute temperature?
Which of the following temperatures is the lowest?
Absolute zero temperature is 0 Kelvin temperature.
What does absolute zero feel like?
So, beside sounding like an awesome band name, absolute zero is the lowest possible temperature in the Universe. At -273.15°C (-459.67°F), it literally can’t get any colder. It’s so cold at absolute zero that the very atoms have stopped moving. That’s really cold.
Can water be below 0 degrees?
Yes, water can stay liquid below zero degrees Celsius.
What does it mean when the temperature is below zero?
4 Answers. It means below zero on whichever scale is in use or generally understood— centigrade, Delisle, or what have you. It would mean the same as freezing in scales where the freezing point of water is set at zero, such as Celsius or Réaumur, but not in scales where zero is set to something else, as in Leiden or Rømer. In Fahrenheit,…
What is a subzero temperature?
In some fields of physics, a “subzero temperature” may even mean a temperature below 0 Kelvin, see e.g. the Wikipedia article on negative temperatures.
What is the temperature of absolute zero?
Absolute zero is the coldest possible temperature that any substance can reach. It is equal to 0 Kelvin or -273.15 °C (-459.67°F). Temperature has an effect on the state of matter.
What is the lowest temperature that can be negative?
Below Absolute Zero: Negative Temperatures Explained. Absolute zero, or 0 degrees Kelvin, is the temperature where all motion stops. It’s the lowest limit on the temperature scale, but recent news articles have heralded a dip below that limit in a physics lab.
