Explanation:
Boiling point: the boiling point of compounds are all different. once a compound in a mixture reaches its boiling point, it will evaporate leaving behind the other compound that is yet to reach its boiling point.

Newton's first law of motion is sometimes called the law of inertia. When the forces acting on an object are balanced, the object is either at rest or moving with a constant velocity. Unbalanced forces can cause an object to accelerate or decelerate. Unbalanced forces can also cause an object to change direction.
