Os etapas que devem sem compridas para obter separadamente os componentes (a as substâncias ) de uma mistura de água ,sal e areia ,são respectivamente : A) filtração e sifonação B) decantação e sifonação C) filtração e destilação simples D) catação e decantação

The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.

Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.

Water molecules is Siphoned, pull by force of gravity through the sand, past  the filter paper to emerge as clean in the beaker below.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
