Dissipation

by Lewis Carroll
written by Lewis Carroll

Dissipation –  in a broad sense, dissipation is the process of reducing the amount of energy, for example, in the process of its utilization. In astrophysics, dissipation is the process by which gases from the atmosphere of space objects escape. Thermal velocities of molecules can exceed the second space velocity, which is the cause of it. Dissipation and volatilization are easiest for those gases whose molecules have smaller molecular weights. As a result, volatile gases such as hydrogen and helium are virtually absent from the atmospheres of the Earth-group planets, which have relatively weak gravitational fields.
