The kinetic theory assumes that collisions of gas particles are perfectly elastic. What does this statement mean?
A. that no energy is lost during each collision
B. that energy is lost in each collision
C. that after each collision, the particles move faster
D. that after each collision, the particles move slower

Question

The kinetic theory assumes that collisions of gas particles are perfectly elastic. What does this statement mean?
A. that no energy is lost during each collision
B. that energy is lost in each collision
C. that after each collision, the particles move faster
D. that after each collision, the particles move slower

rvc · Answer

In perfect collision the energy is not lost. If two objects collide then there will be no motion if the collision is perfectly elastic.
