Question

Define 1J and 1ev

please answer it wrong answer will. be reported​

Answer 1

Answer:

1 eV is defined as the energy gained by an electron when it has been accelerated by a potential difference of 1 volt, hence 1 eV = 1.60210-19J. ... The work function of platinum is highest (Θ0=5.65 eV) and caesium is the lowest (Θ0=2.14 eV).

1 Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied.
