Derivation of cp and cv
WebThe flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other … WebThe minimum energy required to eject electrons from the surface is called the work function. The energy of the incident photon should be greater than the work function. Hence, the conclusion of the photoelectric effect is that the energy in light comes in small packets.
