Aerogel is a manufactured material with the lowest known density of any solid. It is derived from a gel in which the liquid component of the gel has been replaced with a gas. The result is an extremely low-density solid with several remarkable properties, most notably its effectiveness as a thermal insulator and its extremely low density. It is nicknamed frozen smoke, solid smoke or blue smoke due to its translucent nature and the way light scatters in the material; however, it feels like expanded polystyrene (styrofoam) to the touch.
Aerogels are produced by extracting the liquid component of a gel through supercritical drying. This allows the liquid to be slowly drawn off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation. The first aerogels were produced from silica gels. Kistler's later work involved aerogels based on alumina, chromia and tin oxide. Carbon aerogels were first developed in the late 1980s.

What planet is the least dense of the gas giants?
Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water).
What part of the atmosphere is least dense?
The exosphere is the least dense part of the earth's atmosphere.
What is the least dense of the Galilean moons?
Callisto is composed of rock and ice and is the least dense of the Galilean moons.
Which sphere would be the least dense on earth?
The planet Saturn is the least dense of all the planets.I think this is actually about the " four spheres" on Earth.The four "spheres" of the Earth's surface can be described as:atmosphere, biosphere, hydrosphere, and lithosphere.The least dense is the atmosphere.
Where is the air the least dense?
The farther away from the Earth's surface, the less dense the air will be. Of course, once you break out of the atmosphere, there will be no air around you.
What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Is cotton least dense?
'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.
What materials are the least dense?
Gas
What planet is has a big gas giant but the least dense of planet?
Saturn is the least dense planet in our solar system.
Why is it that the least dense of all substances is gas?
The molecules are farther apart in a gas.
What is the least dense thing?
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.

What planet is the least dense of the gas giants?
Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water).
What State Of Matter Is The Least Dense water oil mercury or glass?
Oil will sink in water, so is the least dense.
Which type of planets are least dense?
Gas giants like Jupiter and Saturn are the least dense planets in our solar system. They are made up mostly of gases like hydrogen and helium, making their overall density much lower compared to rocky planets like Earth and Mars.
What is the most dense state of matter to the least dense including solids liquids gases and plasmas?
The order is: - solid (the densest) - liquid - gas - plasma
