The Third Law of Thermodynamics.
"Absolute zero (0 K) is the lower limit of temperature. The temperature of absolute zero cannot be attained physically because to do so would require virtually all the heat to be taken from an object. Therefore, it is impossible to attain a temperature of absolute zero."
What else can I help you with?
How long to Fall to the center of the earth?
it would take 28 hours and 31 minutes give or take falling at an average speed of 140mph.
Suppose a bug is jiggling up and down and swimming towards you at the same time compared to the frequency at which the bug is emitting waves the frequency of the wave reaching you is?
The frequency of the waves reaching you is higher then.
What happen if a cold glass of water left outside on a summer day what happens to it?
In the form of radiation, heat energy will move to the water. (Remember: hot moves to cold and cold can't move!) Eventually, the water will reach the same temperature as the air around it, reaching equilibrium. Hope this helped!
Who was the Clark University physicist responsible for A Method of Reaching Extreme Altitudes?
Robert Goddard
What source does light come from?
Any producer of heat can produce light by reaching enough energy
What are the 4 fundamental laws?
The four fundamental laws of thermodynamics are: the zeroth law (establishes temperature equilibrium), the first law (conservation of energy), the second law (entropy of an isolated system not decreasing), and the third law (impossibility of reaching absolute zero).
How hot is absolute hot?
Absolute hot is a hypothetical temperature at which all thermal motion stops, reaching the maximum possible temperature in the universe. It is estimated to be around 1.416808(33) x 10^32 Kelvin.
Why is it impossible to reach absolute zero?
It is impossible to reach absolute zero because it is the lowest possible temperature in the universe, where all molecular motion stops. The laws of thermodynamics prevent any system from reaching absolute zero, as it would require an infinite amount of energy to remove all heat from a system.
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.
Why is absolute zero only expressed in Kelvin and not celsius?
Because on the Celsius (aka Centigrade) scale, zero is defined as the freezing point of water at standard pressure. On the Kelvin ( aka absolute ) scale zero is defined as the lowest temperature possible - not relative to water or any other substance.
After reaching a low temperature will the temperature of the magnets return to its original temperature?
Yes of Course it will!
Which law of thermodynamics relates to a system reaching o degrees k?
A classical formulation by Nernst (actually a consequence of the Third Law) is: It is impossible for any process, no matter how idealized, to reduce the entropy of a system to its absolute-zero value in a finite number of operations.
What is the lowest temperature that can be attained by matter?
Zero degrees Kelvin, (approximately minus 273 degrees Celsius) which is considered the temperature at which molecules stop moving entirely. Although scientists attempt to replicate this setting in a controlled laboratory setting, it has yet to occur in such a manner.
Why absolute zero is a theoretical concept?
Absolute zero is a theoretical concept because reaching it would require the complete absence of all thermal energy in a system, which is practically impossible to achieve. As temperature approaches absolute zero, quantum effects become dominant and our classical understanding of physics breaks down. Additionally, the Third Law of Thermodynamics states that it is impossible to reach absolute zero through a finite number of processes.
What is the temperature of a meteriod?
The temperature of a meteoroid can vary greatly depending on its distance from the sun and its size. In space, the temperature can be extremely low, near absolute zero. However, when a meteoroid enters Earth's atmosphere, friction with air molecules can cause it to heat up rapidly, sometimes reaching temperatures exceeding 3,000 degrees Fahrenheit.
Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in a star's absolute brightness could be caused by the star moving farther away from Earth, interstellar dust blocking some of its light, or a decrease in the star's temperature. All of these factors would result in less light reaching Earth, causing a decrease in the star's apparent brightness.
Point where all molecules stop moving?
In theory, all molecular motion ceases at absolute zero which is 0 Kelvin (-273.15 degrees Celsius). At this temperature, the molecules have minimal energy and stop moving completely. However, reaching absolute zero is not practically possible.
