The speed of sound in air ~ 340 m/s
in water ~ 1560 m/s in steel ~ 6000 m/s in lead ~ 2000 m/s estimated. Hence, steel is the winner.

NO! Seismic waves can't travel through space. They are mechanical waves. Mechanical waves require going through mediums and there isn't a medium in space.
the answer is sound energy because you have a vibrations in your ear to hear
I would think that their kinetic energy would decrease significantly as they pass through the mediums of increasing density:)
Because of their density, sound waves in the air travel more quickly through the solid and liquid mediums. The energy of a compression wave (such as a sound wave) must pass from atom to atom, which makes the more tightly packed atoms of non-gascious mediums more efficient in transferring sound.
Yes, sound waves can travel through most mediums, even rocks which are extremely dense. A good example is the shock wave from an Earthquake, which can be heard hundreds of miles away from the epicentre after travelling through rocks in the ground.
The answer would be air. The other mediums have higher indices of refraction.
The speed of light, c is greatest in a "vacuum" and is slowed when passing through transparent mediums such as water, glass and crystals. Different mediums reduce the rate of c differently, depending on a number of factors.
in stiff and not stiff mediums stiff mediums are too strong to let the sound wave molecules pass through, whereas less stiff mediums eventually leave the sound waves to loose energy as they pass through. the atmosphere would have to be just right from mediums, no more, no less.
For the same reason anything else changes velocity in a different medium, I would say. A change of electromagnetic impedance in this case
In a vacuum.

Wave motion
When gas travels through different pressures and mediums.
Not all waves require mediums to propagate.Sound waves can travel through solid, liquid and gaseous mediums, while, electromagnetic waves do not require any medium to travel through.
For most mediums, a higher temperature results in higher density, and sound travels through denser mediums faster than through less dense mediums, so a lower temperature generally increases the speed of sound waves.
This depends a lot on the type of waves you're talking about. Sound waves, for example, can travel through water, solid, and air mediums, but not through a vacuum. Electromagnetic waves, however, can travel in a vacuum.
