Answer:
3200 m/s
Step-by-step explanation:
The speed of Sound through Argon is 319.
The speed of sound in any chemical element in the fluid phase has one temperature-dependent value. In the solid phase, different types of sound wave may be propagated, each with its own speed: among these types of wave are longitudinal (as in fluids), transversal, and (along a surface or plate) extensional.
If argon could exist as solid, then 3200 m/s is the best speed.
