Question

Assumption of kinetic theory of gases for real gas

Answer 1

Answer:

The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the ...

Answer 2

Answer:

The basic assumptions of the kinetic theory of an

ideal gas:

(1) A gas of a pure material consists of an extremely

large number of identical molecules.

(2) A gas molecule behaves as an ideal particle, ie., it

has mass but its struchure and size can be ignored as

compared with the intermolecular separation in a

diute gas and the dimensions of the container

(3) The molecules are in constant random motion with

various velocities and obey Newton's laws of

motion.

4) Intermolecular forces can be ignored on the average

so that the only forces between the molecules and

the walls of the container are contact forces during

collisions. It follows that between successive colli-

sions, a gas molecule travels in a straight line with

constant speed.

(5) The collisions are perfectly elastic conserving total

momentum and kinetic energy, and the duration of

a collision is very small compared to the time

interval between successive collisions
