# What Are The Failure Of Classical Statistical Mechanics

## What are the failure of classical statistical mechanics?

Classical or Newtonian mechanics were unable to explain phenomena such as black body radiation, photoelectric effect, and the temperature dependence of a substance’s heat capacity.

## What is the failure of classical mechanics in atom?

Classical mechanics failed to describe experiments on atomic and molecular phenomena : classical physics cannot describe light particles (for example, electrons) a new theory is required (i.e., quantum mechanics)

## What are the failure of classical wave theory?

According to classical wave theory, if light of higher intensity is used, the kinetic energy of an ejected electron can be increased. … However, it cannot explain why maximum kinetic energy is dependent on the frequency and independent of intensity.

## What are the failures of the classical theory of conduction?

2) It fails to explain superconducting properties of metals. 3) It fails to explain new phenomena like photo-electric effect, Compton effect, Black body radiation, etc. 4) It fails to explain electrical conductivity of semiconductors or insulators.

## What are limitations of classical mechanics?

Classical mechanics was unable to explain certain phenomena: black body radiation, the photoelectric effect, and the stability of atoms and molecules as well as their spectra.

## What is the failure of classical physics to explain atomic spectra?

In classical mechanics there would be no discrete energy levels in atom, and indeed no atom itself, for an electron would rapidly lose its energy through radiation and fall to the nucleus. So if you ask how does classical mechanics fail to explain the spectra of elements, the answer is: completely.

## Why classical mechanics fails to explain Compton effect?

Answer and Explanation: This electrons which are oscillating should radiate waves of same frequency. The incident and scattered beams should have same wavelength and frequency. But in Compton effect intensity peaks are present at two wavelengths. Hence the classical theory cannot explain the Compton effect.

## What is the failure of classical mechanics to explain properties of particles at atomic and subatomic level?

Classical or Newtonian mechanics cannot explain such phenomena as black body radiation, the photoelectric effect, or the dependence of the heat capacity of a substance on temperature. Phenomena such as the Chromatin effect, quantum mechanical tunneling, and the Raman effect cannot be explained by classical mechanics.

## What are two failures of wave theory?

This is because the greater the intensity, the larger the energy of the light wave striking the metal surface, so electrons are ejected with greater kinetic energy. However, it cannot explain why maximum kinetic energy is dependent on the frequency and independent of intensity.

## Why classical mechanics fails to explain blackbody radiation?

Classical mechanics couldn’t explain the black body spectrum because the models suggested that particles could vibrate at higher energies without any limit as the intensity increased.

## Why classical mechanics fails to explain photoelectric effect?

Classical mechanics describes light as a wave or as a stream of particles but not both, so any events that depend on photons being both can not be explained by classical mechanics. The photoelectric effect is when no number of red photons will start a reaction but a tiny number blue photons.

## Why classical mechanics fails to explain hydrogen spectrum?

Classical models of the atom before quantum mechanics couldn’t explain why there should only be certain electron energy levels. Hydrogen is a stable atom and its spectrum is discontinuous and was fitted mathematically by the Rydberg series.

## Why classical mechanics fails to explain heat capacity?

Expert-Verified Answer. Explanation: The classical theory, which predicts temperature independent heat capacity, fails to explain why heat capacity tends to zero as temperature approaches absolute zero and is not consistent with the third Iqw of thermodynamics.

## What is the failure of classical theory in the explanation of Compton effect?

Answer and Explanation: This electrons which are oscillating should radiate waves of same frequency. The incident and scattered beams should have same wavelength and frequency. But in Compton effect intensity peaks are present at two wavelengths. Hence the classical theory cannot explain the Compton effect.
