For an ideal gas, they are are perfectly elastic. Option A
The kinetic molecular theory states that there is perfect elastic collision between gas particles in an ideal gas. This indicates that there is no kinetic energy lost during collisions and that the particles bounce back without changing permanently.
According to the theory, gas particles can move independently because they are point masses with very little volume. The kinetic molecular theory of ideal gases is at odds with other possibilities, such as particles changing permanently, adhering to one another during collisions, or only colliding at extremely low temperatures.
Missing parts;
According to kinetic molecular theory, collisions between gas particles in a sample of an ideal gas:
A) Are perfectly elastic.
B) Lead to permanent changes in the gas particles.
C) Cause the gas particles to stick together.
D) Only occur when the temperature is very low.
