Speed of sound in different media at 25 degree Celsius

Last updated on November 9th, 2023 at 03:18 pm

Sound travels at a speed that is much less than the speed of light.

The speed of sound depends on the properties of the medium through which it travels. The speed of sound in a medium depends on the temperature of the medium. [ see more: how speed of sound changes with temperature change]

  • The speed of sound decreases when we go from a solid to a gaseous state.
    In any medium as we increase the temperature, the speed of sound increases.
  • For example, the speed of sound in air is 331 m/s at 0 oC and 344 m/s at 22 oC.

The speeds of sound at a particular temperature in various media are listed in Table 1.
