thermionic emission occurs when the filaments are heated to a certain degree, causing the electrons to boil off and form a space charge or electron cloud.
Thermionic emission occurs at the cathode in a cathode ray tube, which is a vacuum tube that generates electron beams. When the cathode is heated, electrons are emitted and accelerated towards the anode, leading to the generation of cathode rays within the tube.
Thermionic emission is the process by which electrons are emitted from a heated metal surface, while evaporation is the process by which molecules in a liquid state gain enough energy to escape into the gas phase. Thermionic emission specifically involves the emission of electrons, whereas evaporation involves the transition of molecules from a liquid to a gas phase. Additionally, thermionic emission typically occurs at high temperatures, while evaporation can occur at a wide range of temperatures depending on the substance.
Seminal emission refers to the release of semen from the penis during ejaculation. It can occur during sexual activity or while dreaming and is a normal physiological process for males.
Electrons can be emitted from copper metal through a process called photoemission, where photons of sufficient energy strike the copper surface, imparting energy to the electrons and overcoming the work function of the material. Alternatively, thermionic emission can occur when the copper is heated, providing enough thermal energy to allow electrons to escape from the metal's surface. Additionally, in a vacuum, applying a strong electric field can facilitate the emission of electrons through field emission.
Mottling occurs when the dye migrates during the granules' drying process.
Combustion occur and emission
Yes, most inheritable differences occur during the production of gametes through processes like gene shuffling during meiosis. This leads to genetic variation in offspring as a result of the combination of genetic material from two parents.
The production of glucose takes place during the light independent reactions (Calvin cycle) in the Stroma.
During The Calvin Cycle cycle, sugars are produced in the chloroplast.

Emission refers to the release of radiation from a source. This can occur in various forms such as light, heat, or particles. Emission can either increase the intensity of radiation or change its properties, depending on the source and energy involved.
yes, this happens both when men and women go through puberty
