Potential energy is when the particles are at rest and kinetic energy is when the particles are in motion.

A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?

Volts. Volts is another term for potential.


What is an example of kinetic energy transferred to potiental energy?

Any object which is moving from a lower level to a higher level is converting kenetic energy (ie climbing a set of stairs for example) to potential energy. A car which has been parked at the top of a hill has used kenetic enegry to get up there and has potential to roll down to the bottom of the hill if the brake is released.


Whats the difference between activation energy and the change of energy in a PE diagram?

Activation energy is the minimum energy required for a reaction to occur, while the change in energy in a potential energy diagram represents the difference in energy between the reactants and the products of a reaction. Activation energy is specific to the transition state of a reaction, whereas the change in energy is a measure of the overall energy difference between reactants and products.


What is the si unit for potential energy difference?

Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)


The reaction below shows how the potential energy changes during a chemical reaction. How is the change in enthalpy shown on the graph?

The change in enthalpy during a chemical reaction is represented on the graph as the difference in potential energy between the reactants and the products. If the products have lower potential energy than the reactants, the enthalpy change (ΔH) is negative, indicating an exothermic reaction. Conversely, if the products have higher potential energy, ΔH is positive, signifying an endothermic reaction. This difference is visually depicted by the vertical distance between the starting and ending points on the potential energy axis.
