Science (New York, N.Y.)
|October 19, 1990
Summary
Triton
Area of Science:
- Planetary Science
- Atmospheric Science
- Aeronomy
Background:
- Triton exhibits tall plumes, suggesting atmospheric phenomena.
- Terrestrial dust devils offer a potential analog for Triton's plumes.
Purpose of the Study:
- To investigate the atmospheric dynamics of Triton's plumes.
- To explore the possibility of dust devil formation on Triton.
Main Methods:
- Comparative analysis of plume structure with terrestrial dust devils.
- Application of atmospheric physics principles to Triton's conditions.
- Utilizing Voyager radio science data for temperature validation.
Main Results:
- Triton's plume structure is consistent with atmospheric vortices.
- Low surface pressure on Triton facilitates unstable atmospheric layers.
- Modeled dust devil velocities reach 20 m/s under specific conditions.
- Particles with low cohesion could be lofted by these winds.
Conclusions:
- Triton's plumes are likely atmospheric phenomena, possibly dust devils.
- Convection driven by surface heating can generate strong winds on Triton.
- The low cohesion of Triton's surface particles is key to plume formation.

01:20Momentum And Radiation Pressure
An object absorbing an electromagnetic wave would experience a force in the direction of propagation of the wave. This force occurs because electromagnetic waves contain and transport momentum. The force accounts for the wave's radiation pressure exerted on the object. Maxwell's prediction was confirmed in 1903 by Nichols and Hull by precisely measuring radiation pressures with a torsion balance. The measuring instrument had mirrors suspended from a fiber kept inside a glass container. Nichols...
00:52Washing, Drying, and Ignition of Precipitates
After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...
02:35Clausius-Clapeyron Equation
The equilibrium between a liquid and its vapor depends on the temperature of the system; a rise in temperature causes a corresponding rise in the vapor pressure of its liquid. The Clausius-Clapeyron equation gives the quantitative relation between a substance’s vapor pressure (P) and its temperature (T); it predicts the rate at which vapor pressure increases per unit increase in temperature.
01:27Diversity of Protists III
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...
01:11Dalton's Law of Partial Pressure
The partial pressure of a gas is a measure of the thermodynamic activity of the gas's molecules. The pressure that a gas would create if it occupied the total volume available is called the gas's partial pressure. If two or more gases are mixed together in a container, the molecules move randomly and collide with each other, causing them to reach thermal equilibrium. When the gases have the same temperature, their molecules have the same average kinetic energy. Thus, each gas obeys the ideal...
01:19Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview
In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then passed on to...
