dissipation
n. uncountablen. the process of energy or heat spreading out and being lost to the surroundings. In physics, it often describes how a wave or signal weakens as it moves through a medium.
n. the process of energy, heat, or matter being dispersed or lost to the environment. In a physical context, it refers to the reduction in the amplitude of a wave or signal as it propagates through a medium.
The dissipation of heat is important for cooling electronic devices.
Engineers must account for the dissipation of energy in the transmission lines to ensure the signal remains strong at the receiver.
The rapid dissipation of the storm's energy over the cold ocean waters prevented it from reaching the mainland with its full force.
From Middle English dissipacion, dissipacioun, from Late Latin dissipātiō. Morphologically dissipate + -ion.
