The speed of a sound in a container of hydrogen at 201K is 1220m/s. What would be the speed of sound if the temperature were raised to 405K? Assume that hydrogen behaves like an ideal gas.

Please guide me to do it. Thanks!
Answered by drwls
The speed of sound is proportional to the square root of the absolute temperature.

Therefore, multiply 1220 m/s by sqrt(405/201)

It's an Ideal gas law problem, set both equal to K (or k if you are a chem major) and set them equal to each other. Get rid of everything that is on both sides and hen solve for the unknown velocity.

v2=sqr((T2*v1^2)/T1)
