Speed of Sound

Today we talked about whether sound would travel the fastest through a solid, liquid or gas. We demonstrated by acting as molecules. We stood in three separate lines, different spaces apart (one for solid, one for liquid, and one for gas).

Sound travels the fastest through a solid because the particles are closest together and therefore the particle to particle interaction can happen the fastest.

Speed of Sound in Different Mediums

The speed of sound in air is around 20 degrees Celsius is 343 m/s or 768 mph. We watched videos of different air crafts breaking the speed of sound and Felix Baumgartner breaking the speed of sound when he "sky dove" from 26 miles above Earth's surface.


We played more instruments the last couple of minutes of class.
