The speed of sound in air increases with temperature, as the density of the air decreases.
When they are hotter.
I would think in warmer Air....

Sound can travel, more or less, through any matter, but not at all through a vacuum. The main factors that affect the speed of sound are as follows: Temperature: Hotter materials allow sound to travel faster Density: Sound travels faster in denser materials Elasticity: This means the ability for the molecules of a material to bounce back to their original positions quicky. The more elastic a material, the faster sound can travel through it.
They travel faster through solids
The denser the faster. ie: it will travel faster through quartz than sandstone.
sound travel faster through soled because of tighter packed particles
sound travels faster through steel
faster apex.....................................................................................................................
Through metals
It doesn't travel faster through a vacuum. In our Universe there is no such thing as empty space.
