[itex]C_v[/itex] : Specific Heat at constant volume

Also [itex]C_p - C_v = R[/itex]

[itex]\frac {C_p}{C_v} = lamda[/itex]

where lamda = [itex]1 + \frac {2}{f}[/itex]

Where f=degrees of freedon

for monoatomic gas , f=3

for diatomic gas , f=3

You can solve for two expressions at the top to get Cp

One correction to Dr.Brain's post. f for diatomic gases is 5

And that's only at around room temperature's where the vibrational degree of freedom is absent. At high temperatures, f will be 7 for diatomic gases.quark said:One correction to Dr.Brain's post. f for diatomic gases is 5
