Find the speed of sound in air at a temperature of 250 K.
Find the speed of sound in air at a temperature of 250 K.
Speed of sound is given by \[a = \sqrt {\gamma RT} \]
Speed of sound depends on the type of the medium and its temperature. In air it depends on the type of the gas and its temperature. On Earth, atmosphere is composed of mostly nitrogen and oxygen and temperature varies with the altitude.
\[a = \sqrt {1.4 \times 287 \times 250} = 316.94\,m/s\]
Mars has an atmosphere which is composed mostly of carbon dioxide.
