What is the driving force of phase change?

The driving force of a phase change is a change in the energy state of the substance. This can be caused by a change in temperature or pressure, which alters the balance of forces between the particles in the substance, leading to a transition to a different phase.

Why wouldn't a double replacement reaction occur?

A double replacement reaction may not occur if the possible products are insoluble or if there is no driving force for the reaction to proceed. Additionally, if the reactants do not contain the necessary ions to exchange partners, a double replacement reaction may not occur.


What does force always do?

Forces always occur in pairs. They even have reaction force pairs occur when there is no motion


When one bumper car hits another how does the reaction force affect the first car?

When one bumper car hits another, the reaction force from the second car pushes back on the first car. This can cause the first car to slow down, change direction, or even spin depending on the impact force and angle of collision. The first car will experience a change in momentum due to the reaction force from the collision.


What is a reaction force and formula?

The idea of a reaction force comes from Newton's third law; "If object A exerts a force on object B ,then object B will exert an equal but opposite force back on A". In many problems some of the forces are considered as the "initiating" force or the applied force. When you consider a force as being applied, like a bulldoser pushing a rock, then the force which must act back , the rock pushing back on the doser, is called the reaction force. Sometimes you don't really have an initiating force but it still convienient to think of one force as the force of interest and the back force as the reaction force. There is no single formula for reaction force since it can apply to any force. For example, the earth attracts you with a force mg (your weight), then you can think of the reaction force as you attract the earth with a force -mg; equal but opposite.


Does the mass of an object affect friction-?

Yes Friction=Reaction force x COF Reaction force = mass x gravity So Friction=mass x gravity x COF ^ Change the mass, change the friction


How is competition a driving force in society?

Competition would be the driving force of exclusion


How can there be an unbalanced force on an object if every action has an equal and opposite reaction?

"action/reaction" does not mean " force". "Applying force" is an action, not the force itself. So, applying force will create a reaction, which may or may not balance the applied force.


What is meant by the term driving forces?

driving force is the opposite force against (air resistance, friction, drag, tension) it is the force provided by some kinda potential, A car engine provides driving force or in fact any kinda force to keep the object moving
