Two particles of a gas collide. Why is this considered an elastic collision?(1 point) Responses They bounce off each other, conserving momentum only. They bounce off each other, conserving momentum only. They bounce off each other, conserving energy and momentum. They bounce off each other, conserving energy and momentum. They bounce off each other, conserving energy only. They bounce off each other, conserving energy only. They stick together, conserving momentum.

Answer 1

The correct response is: They bounce off each other, conserving energy and momentum.

In an elastic collision, both momentum and kinetic energy are conserved. This is characteristic of ideal gas particles, which are often modeled as undergoing elastic collisions.
