Why is absolute zero
theoretical?
A. All particles in a sample can never all
be moving at once.
B. All particles in a sample can never stop
moving.
C. Zero degrees Celsius is impossible.

Respuesta :

Answer:

b

Explanation:

The Theoretical temperature ie, Absolute Zero is when "All particles in a sample can never all be moving at once." Hence, Option (A) is correct

What is Absolute Zero temperature ?

It is determined by  ideal gas law;  absolute zero is taken as −273.15 degrees on the Celsius scale (International System of Units), which equals −459.67 degrees on the Fahrenheit scale.

Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.

The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion.

According to the laws of thermodynamics,

Absolute zero cannot be reached using only thermodynamic means, because the temperature of the substance being cooled approaches the temperature of the cooling agent asymptotically and a system at absolute zero still possesses quantum mechanical zero-point energy, the energy of its ground state at absolute zero.

The kinetic energy of the ground state cannot be removed.

Therefore,

The theoretical temperature ie, Absolute Zero is when "All particles in a sample can never all be moving at once." Hence, Option (A) is correct
