How do you calculate the CP of a gas mixture?

In short the specifics heats Cp & Cv of a gas mixture are not that given by the sum of specifics heats of the individual gases. They are equal to the sum of (mass fraction x heat specific) related to individual gas. If cp or cv is given in kJ/kgK multiply by the mass fractions.

How do you calculate CP CV ratio?

The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Monoatomic gas has only one translational motion, hence three translational degrees of freedom.

Why does Sea water boils above 100 degree Celsius?

At sea level, vapour pressure is equal to the atmospheric pressure at 100 ˚C, and so this is the temperature at which water boils. Due to this, the temperature required to reach the necessary vapour becomes lower and lower as we get higher above sea level, and the liquid will therefore boil at a lower temperature.
