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.
What else can I help you with?
What happens to molecules when the temperature reaches absolute zero?
by the laws of thermodynamics, nothing can ever reach absolute zero. Theoretically, molecular motion would stop. They would still be molecules, they would just not move.
When do molecules have the lowest amount of energy?
When they are the coldest that they can be is when they have the least energy. Absolute Zero is when molecules have no energy and are not moving, but it is impossible to get to that degree.
What is the absolute zero theory?
Absolute Zero is 0 degrees Kelvin (0K) or −273.15° Celsius. It is the point where all molecular movement associated with entropy ceases. It is used in equations such as the Ideal Gas Law: PV=nRT See a good summary on wikipedia: http://en.wikipedia.org/wiki/Absolute_zero
What temperature do particles stop moving?
That happens at the "absolute zero" of temperature, also called zero kelvin. In fact, according to quantum theory there is still a very small amount of motion of particles even at zero kelvin. Also, it's theoretically impossible to reach absolute zero, but we have got very close to it.
Can hydrogen be a solid?
Yes, but only at absolute zero, which has not been reached yet. For all intents and purposes it will never happen, as absolute zero is almost impossible to reach as heat is being transfered as long as there is contact.
Would you say that a dead body would reach absolute zero?
Nope; it would never go below room temperature. It is technically impossible to reach absolute zero
Why is it impossible to reach absolute zero?
Reaching absolute zero (-273.15 degrees Celsius) is impossible because as an object reaches lower temperatures, its atoms eventually stop moving completely, which is against the laws of physics. This would violate the Third Law of Thermodynamics, which states that it is impossible for any system to reach absolute zero in a finite number of steps.
What is the third law of thermodynamics, which states that no system can reach absolute zero temperature?
The third law of thermodynamics states that as a system approaches absolute zero temperature, its entropy approaches a minimum value. This means that it is impossible for any system to reach absolute zero temperature.
Why is it imposible to attain the absolute zero temperature?
Attaining absolute zero temperature is impossible because it represents the complete absence of thermal energy in a system, which is practically unattainable. As thermal energy decreases, it becomes increasingly difficult to remove the last remaining trace of energy to reach absolute zero. Additionally, the third law of thermodynamics states that it is impossible to reach absolute zero through a finite number of processes.
Which law of thermodynamics states that it is impossible to reach absolute zero?
An object can never reach absolute zero in kinetic terms because there is never a total lack of kinetic energy, molecules are always moving.
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.
Do molecules disappear at absolute zero?
No. They are as frozen still as they can ever be. It is said to be scientifically impossible to actually reach absolute zero.
Why might it be especially difficult for scientists to cool a substance all the way down to absolute zero?
Cooling a substance to absolute zero is challenging because as the substance gets colder, it loses energy. At absolute zero, the substance would have no thermal energy, which goes against the principles of quantum mechanics. Additionally, achieving absolute zero requires overcoming the third law of thermodynamics, which states that it is impossible to reach absolute zero through a finite number of steps.
What is the coldest thing?
On the Kelvin scale zero is considered the coldest temperature one can reach: absolute zero. It is the point at which it is impossible to get any colder. 0.00 K is -273.15 oC or -459.67 oF.
Why can't -5K exist?
0K is absolute zero, meaning that the system contains zero thermal energy. Temperatures below absolute zero are impossible.
What is the lowest temperature that a substance can reach?
The lowest possible temperature a substance can reach is absolute zero, which is 0 Kelvin or -273.15 degrees Celsius. At this temperature, particles have minimal thermal energy and motion ceases, making it impossible to extract any more heat from the substance.
Can space reach absolute zero?
NO, this is impossible. 0 K, or -273 *C can never be reached. In deep space, it can be 0.1 K or so, which is really cold. Heat 'spreads' from a hotter place to a colder, so if there were ever a place with absolute zero, some heat would immediately go there. Then, that point would probably reach a point possibly just above absolute zero.
