Question

in ideal gas collisions present between molecules

Answer 1

gas molecules are in constant random motion with high velocities that moves in a straight line and changes their directions on a collisions with other molecules or Walls of the container.

the collisions are perfectly elastic, therefore there is no loss of kinetic energy during collisions.however there may be re distribution of energy during such a collisions.

Answer 2

The term ideal gas refers to a hypothetical gas composed of molecules which follow a few rules: Ideal gas molecules do not attract or repel each other. The only interaction between ideal gas molecules would be an elastic collision upon impact with each other or an elastic collision with the walls of the container.
