velocity of sound

None

AS WE KNOW

THEN WHY <V> NOT DPEND ON PRESSURE?

if temperature remains tha same,then pressure and density maintain a constant ratio and hence speed does not change but if temperature changes speed changes as v is propotional to (T)^1/2

It is not only a function of P but its a function of P/

.Suppose you vary pressure at constant temperature then density,

is itself varied in such a way that P/

is constat.

PV = nRT
=> PM =

RT
=> P/

= RT/M

Hence it depends on ratio of P/

which in turn is directly proportional to temperature.
