FIX THIS:Identify the postulate /s which help to formulate a mathematical model of gases. i) A finite volume of gas consists of very large number of molecules ii) The size of the molecules in much smaller than the separation between molecules. iii) Molecules do not exert force on each other except during a collision
Correct answer: E. I, II and III
- A. I only
- B. II only
- C. III only
- D. I and II only
- E. I, II and III
Explanation
Explanation:i) Postulate I states that a finite volume of gas is composed of a very large number of molecules. This assumption allows us to treat gases as continuous media, even though they are composed of discrete particles.ii) Postulate II states that the size of gas molecules is much smaller than the separation between them. This assumption is essential for treating gas molecules as point particles and simplifies the mathematical modeling of their behavior.iii) Postulate III states that gas molecules do not exert force on each other except during collisions. This assumption is fundamental in the kinetic theory of gases and is crucial for developing the mathematical models that describe gas behavior.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
