Sound is a mechanical wave, so it can't travel in vacuum. Sound speed will be higher
when the molecules of the material it is traveling are closer to each other, this means
that it travels the fastest in solids, medium speed in liquids and slower in gases.
In vacuum, the speed of sound is zero. Sound doesn't propagate through vacuum.
Shout as loud as you want to, and the sound goes nowhere if there's no medium to
carry it. Two astronauts standing next to each other on the surface of the moon
can communicate only by radio, or by touching their helmets together.

Sound travels faster in iron. Usually sound travels faster in media with higher density. Also presence of lattice makes difference too.
That completely depends on what "slowly" means to you.Sound propagating through iron is quite slow compared to the speed of lightin vacuum, but is substantially faster than the same sound in air.
sound travels the fastest in solids, then liquids, then gas. So it would travel through iron the fastest, then water, then air.

Sounds travel best in solids that are of high density so sound travels fastest in iron.
Sound travels via particle-to-particle vibrations around a mean position; this means that the more particles there are, the better the sound travels. Therefore, sound travels faster through iron than through water or air. Sound travels through iron roughly 15 times faster than through air. The more dense the solid, the better the sound transfer. Sound will travel the fastest in solids since the molecules are more tightly packed together, allowing sound to travel through the medium faster. Then comes liquids, then gases. Sound travels fastest on earth because there is no sound in space! since there's no medium in space for sound to travel through.
sound passes fastest through glass
Sound will travel through all of those.

One source on the Internet (http://www.bamr.co.za/velocity%20of%20materials.shtml) has the speed of sound in various glasses between 4260 and 6800 m/s and that source has the speed of sound in steels 5900 to 6100 and cast iron 3500 to 5600 So according to that source the speed of sound is comparable in both iron and glass with the variations giving lower speeds in some iron compounds/manufacturing states then the lowest speeds in glass and some glasses having higher speeds than steels.
