Given: For Oxygen

P=100 kPa (abs)(Pressure)

T=250C=25+273=298K(Temperature)

R=260J/kg.K(Ideal gas constant)

k=1.4 (Adiabatic constant)

To find:

c(Speed of sound)

For Oxygen at the given temperature and pressure, we know that the sound in oxygen is given by

c=kPρ

But, By Ideal gas equation

PV=mRT

Pρ=RT

Hence, …
