40 degrees
Sound travels faster in a medium at a higher temperature. Therefore, sound will travel faster at 88 degrees Celsius compared to 58 degrees Celsius.
The denser the faster. ie: it will travel faster through quartz than sandstone.
58 degrees because it is closer to 69 degrees.
sound travel faster through soled because of tighter packed particles
Waves travel faster through denser materials. However, Electromagnetic waves travel faster through less dense materials. It travels fastest in vacuum.
Light travels much faster than sound, through wood.
Sound
Air.
15 times faster
sound travels faster through water than air.
no sound travels faster through solids.
I believe that sound travels faster through iron because it bounces off the sides, and causes it to travel faster, reaching the other side.
