What temperature does an object emit electromagnetic radiation?
At absolute zero (O K or -273.15 degrees Celsius), there is no energy radiated. The wavelength of light emitted is related by Wien's Law: (lambda) = 3x10^-3/T Where lambda is the wavelength of the radiation. T is the temperature in Kelvin. When T approaches 0 K, the wavelength of the emitted radiation approaches infinity (lower energy). At zero, there is no emitted energy.
Why it is impossible for anything to be colder than the lowest possible temperature?
Because - 'absolute zero' (0 Kelvin or -373 Celsius) - is the temperature at which everything freezes. Scientific testing has not found any substance or object that does not freeze below absolute zero.
Do hot objects absorb infrared radiation?
All objects emit (give out) and absorb (take in) thermal radiation, which is also called infrared radiation. The hotter an object is, the more infrared radiation it emits. However; the hotter an object, the faster it will emit infrared radiation. Even though hotter objects can absorb infrared radiation, they will continue to emit infrared radiation much faster than they absorb it from any colder objects / sources around them, until an equilibrium is achieved with the objects surroundings i.e. it is always an antagonistic relationship with the objects surroundings and the surroundings with the object.
What temperature scale has zero as it's lowest temperature?
The Kelvin scale (apex)
What is subzero temperature?
any temperature lower than zero
Can you give an example of a simple sentence using the word absolute zero?
Absolute Zero is the temperature at which everything freezes.
What is a good sentence for temperature?
Absolute Zero is the temperature at which everything - even atoms - freezes.
What is the temperature of raidation zone in kelvin?
Everything above zero.
What emit radiation?
anything hotter than absolute zero temperature
What types of matter does radiation happen in?
Electromagnetic radiation is emitted by all matter not at a temperature of absolute zero. Since it is impossible by both thermodynamics and quantum mechanics for any matter to be at a temperature of absolute zero, all matter emits electromagnetic radiation. If you were instead asking about radioactivity... only radioactive isotopes and highly energetic stellar and cosmological phenomena emit that.
What state would oxygen be at temperature absolute zero?
At absolute zero molecules are not supposed to move, so in theory everything would be a solid
How much degrees celsius does it get to in space?
Absolute zero is -273.15oC. The temperature in space is about 3 Celsius degrees above absolute zero, or -270.15oC. The background radiation temperature is about 3 degrees Kevin. The local temperature would depend on how close you are to a heat source such as a sun
Why the inorganic substance not give infrared spectrum?
Any substance, organic or otherwise, will give off infra red radiation if it is above absolute zero. Even a substance that is absorbing radiation will emit some.

Why is -273point15 degrees C the minimum temperature?
It is absolute zero, the temperature where there is zero energy and zero entropy. This temperature is unobservable.
If kelvin absolute zero is -273 what substance is that cold?
"Absolute zero" (Zero Kelvin) is a theoretical temperature, at which all atomic motion stops. This temperature can't be reached in practice, but we can get very close. Laboratories on Earth have reached temperatures of less than a microKelvin (millionth of Kelvin, or millionth of a degree from absolute zero). In outer space, it usually doesn't get much colder than about 3 Kelvin, because of a background radiation equivalent to that temperature.
How low can the temperature go anywhere in the universe?
The average temperature of the universe now is 2.72548K (the cosmic blackbody radiation of the big bang cooled by expansion). There are places colder, but nothing can be as cold as 0K (absolute zero).
