Why would gas take up more volume than any of the solids?

Answer 1

Gas is matter in a relatively high temperature range, where the molecules bounce off each other, at relatively high speeds, which makes gas take up a lot more space.

Additional Information:

At a certain temperature and pressure, all materials have a point where the individual atoms in the element or compound have enough energy to disrupt the type of bond that rendered it a solid. More can be read about the different types of bonds here:http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/bond.html

Depending on the material, the pressure, and the temperature, the volume of a gas will usually take up more space than a solid, but it is certainly plausible to have a gas that takes up less space than a solid if the temperature and pressure are high enough. The equation PV=nRT (ideal gas law) is a good approximation of what to expect at different temperatures for different substances. Van Der Waal, Maxwell, Pauli, and Plank also came up with interesting equations concerning the unusual behaviour of matter when various interesting things are done to it that involve pressure, heat, and volume.

Answer 2

Simple answer really. There are some form of solids that are malleable. A solid

Answer 3

One kilogram of gas has a larger volume than 1 kg of a solid because is molecules are more widely dispersed.
