In a collision between a light hydrogen molecule and a heavy water molecule,the momentum lost by one molecule is exactly the same as the momentum gained by the other molecule.

Question

Quizplus · Accepted Answer

According to the law of conservation of momentum, the total momentum in a closed system remains constant. In this case, the system consists of two molecules colliding with each other. Therefore, the momentum lost by one molecule would be equal to the momentum gained by the other molecule. This implies that the total momentum of the system is conserved, which is true according to the law of conservation of momentum.
