Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid.Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.The word "surfactant" is a blend of surface-active agent, coined c. 1950.. Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame; this is different from coordinate acceleration, which is acceleration in a fixed coordinate system.For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due Agents that increase surface tension are Because of target translucence, applications that use infrared sensors, for example, struggle with this particular use case for liquid level measurement.
