What is conserved during the elastic collision of gas molecules? Explain.

(N/A) During the elastic collision of gas molecules,both the total linear momentum and the total kinetic energy of the system are conserved.
$1$. Conservation of Linear Momentum: According to Newton's laws,in the absence of any external force,the total momentum of the colliding particles remains constant.
$2$. Conservation of Kinetic Energy: In an elastic collision,there is no loss of energy to other forms such as heat,sound,or deformation. Therefore,the sum of the kinetic energies of the molecules before the collision is equal to the sum of the kinetic energies after the collision.
These conservation laws are fundamental to the Kinetic Theory of Gases,which assumes that gas molecules behave as hard,perfectly elastic spheres.
