WebFor a monoatomic ideal gas, the adiabatic constant is 5/3, and for a diatomic gas (such as nitrogen and oxygen) adiabatic constant is 7/5. For molecules with three atoms, it is 4/3. With an adiabatic constant 5/3 and molecular mass 4 g/mol for helium, the sound speed at 20C is 1007 m/s. That's why the voice in helium sounds so funny. WebConstant pressure = J/mol K: Constant volume = J/mol K: The specific heats determine the ratio, = Note that the value of γ is determined by the gases, the most common values being γ air = 1.4 and γ monoatomic gas = 1.66 .
