what i have found so far is that the speed of sound in a fluid,c, is equal to the sqaure root of the bulk modulus,k, diveded by the density of the fluid,p.

c=(k/p)^0.5 (sorry i dont know how to use equations on this).

iv also found that the bulk modulus is equal to the voulume, v, times by the difference in pressure,dp, over the difference in volume,dv.

k = v(dp,dv)

but what i would like to know is how the bulk modulus relates to temperature. any ideas?

many thanks
