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 else can I help you with?
Will a solid flow up?
This depends on how dense the solid is, and how dense the liquid is.
What is more dense?
a solid is more dense
Which cold solid is less dense than the liquid when it melts?
Ice is a solid less dense than the liquid
Is solid ice more dense than water?
No. It is less dense.
Does a solid get more dense if its volume increases?
No. It gets less dense
Is ice cube a solid gas or liquid?
solid with hydrogen bonds making it less dense than its liquid form
What is less dense?
a solid that sinks in water
Is water less dense when it is a solid?
yes
What is less dense gas or solid?
gas
Can a solid be more dense than a liquid?
Yes, a solid can be more dense than a liquid. Density is defined as mass per unit volume, so a solid with a higher mass per unit volume than a liquid will be more dense. An example is comparing ice (solid) to water (liquid), where ice is more dense than liquid water.
What is the least dense solid element?
Aerogels - but this is an artificial compound. Among naturally occurring metals, Lithium (Li).
What is the solid dense center of our planet?
The solid dense center of our planet is called the inner core. It is made of an iron nickel alloy and has a temperature similar to the sun.
