Internal photoemission is a process in which a photon with sufficient energy is absorbed by a material, causing an electron to be emitted from the material. This electron emission occurs within the material itself, as opposed to from the material's surface. Internal photoemission is often used in the study of electronic properties of materials, such as bandgap measurements in semiconductors.

How is internal energy defined?
Internal energy is the sum of all microscopic kinetic and potential energies of the particles within a system. It includes the energy associated with the motion and interactions of atoms and molecules. Internal energy is a state function, meaning it depends only on the current state of the system and not on the path taken to reach that state.
What is the meaning of internal heat generation?
Internal heat generation refers to the production of heat within a system or object as a result of various processes such as chemical reactions, friction, or electrical resistance. This phenomenon can lead to an increase in temperature within the system, impacting its overall thermal properties and performance.
What happens to internal energy when mechanical work is done?
When mechanical work is done, the internal energy of a system can change. If work is done on the system, the internal energy increases. Conversely, if work is done by the system, the internal energy decreases. This change in internal energy is governed by the first law of thermodynamics.
A force of 315N is applied to a crate to displace it 35m across a floor at constant velocity The internal energy increases by 14percent of initial internal energy what was the initial internal energy?
The work done by the force is calculated as the force applied multiplied by the displacement, which gives W = 315N * 35m = 11025 J. Since the crate is moving at a constant velocity, the work done by the force is equal to the increase in internal energy. Given that the increase in internal energy is 14% of the initial internal energy, we can calculate the initial internal energy as I = 11025 J / 0.14 = 78750 J.
When system does work what happens to it's internal energy?
When a system does work on its surroundings, its internal energy deceases. This is because some of the internal energy of the system is being used to perform the work.
What does internal meaning mean?
internal means on the inside or within something
