Question:
According to kinetic theory of gases?
heavier molecules transfer more momentum to the wall of the container
collisions are always elastic
only a small number of molecules have very high velocity
between collisions, the molecules move in straight lines with constant velocities
Solution:
Kinetic Molecular Theory of gases is based on following postulates:
A gas consists of a large number of particles, called molecules, and they are so small that their actual volume is a negligible fraction of the total volume occupied by the gas.
The molecules are in constant rapid motion in all possible directions, colliding in a random manner with one another and the walls of the container.
Both the collisions are perfectly elastic so that there is no net loss of energy. The kinetic energy may be transferred from one molecule to another but not converted to any other form such as heat.
The correct option is only A.
