No external forces. Objects may bounce off each other, or merge but the total momentum is unchanged even when the total energy changes.

When two objects collide the momentum of the pair after the collision is explain by which of newton's law?

Newton's Third Law. Newton's Laws are the Conservation of Energy. Conservation of Energy indicates the sum of the forces is zero. This condition force is zero; 0 = F= dP/dt =0 means P, Momentum is constant or conservation of Momentum..

How can before and after situations be compared for collisions using the law of conservation of momentum?

The momentum before and after is the same, due to the Law of Conservation of momentum. Thus if you calculate the momentum before, then you have the after momentum or vice-versa.
