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.
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.
What happens to thermal energy when temperature decreases?
When the temperature decreases, thermal energy decreases as well. This means that the particles in the object have less kinetic energy and move more slowly. If the temperature continues to decrease, the object may eventually reach a point where all motion stops and it reaches absolute zero temperature.
What is meant by the term absolute zero Why can't an object actually be that cold?
Absolute zero is the theoretical temperature of an object that has no kinetic energy. This is 0 on the Kelvin scale which relates to -273.15oC. Nothing can actually reach this temperature as to achieve a kinetic energy of 0 Joules, the object would have to be removed from the universe entirely.
What happens at zero degrees in the kelvin scale?
At zero degrees Kelvin, also known as absolute zero, all molecular motion stops. It is considered the coldest temperature in the universe, and no physical object can reach this temperature in reality.
What is lowest temperature that the substanc can reach?
Temperatures can approach, but never reach, absolute zero. This is about -273 degrees C.
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.
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
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.
Is it possible to reach a temperature lower than absolute zero?
no

How do you get the absolute zero temperature?
All energy must be removed from the atoms. All atoms in the substance you want to reach absolute zero have to remain absolutely still, meaning that not even a single atom can move. If you take a piece of paper, you may think that the atoms of the paper are not moving, but they are actually vibrating. Thus, for a solid object to reach absolute zero, all atoms must stop vibrating.
What happens at zero degrees in the kelvin scale?
At zero degrees Kelvin, also known as absolute zero, all molecular motion stops. It is considered the coldest temperature in the universe, and no physical object can reach this temperature in reality.
If is transferred from object a to object b the temperature of object a decreases?
When heat is transferred from object A to object B, the temperature of object A decreases because it is losing thermal energy to object B. Heat transfer occurs from the object with higher temperature to the object with lower temperature in an attempt to reach thermal equilibrium.
What is the coldest temperature that ice can reach?
The coldest temperature that ice can reach is -273.15 degrees Celsius, also known as absolute zero. At this temperature, all molecular motion stops, making it the lowest possible temperature.
