Choose the statement(s) that is/are true about the ratio \frac{C_p}{C_v} C p C v for a gas? (Ii) This ratio is the same for all
gases. (ii) This ratio has a value 1.67 for a monatomic gas (iii) This ratio has an approximate value of 1.4 for diatomic gases. (iii) This ratio has a value 8.314\:J.mol^{-1}.K^{-1}
(i) The ratio of Cp and Cv is not constant for all the gases. It is because the value of cp and Cv is different for monoatomic, diatomic and polyatomic gases.
I was struck by this many years ago while in graduate school. ... People with mental illness tend to die young , but so do their families. ... there is no medical assessment that can diagnose the absence of illness.
