(one mole of any ideal gas) For a monatomic ideal gas, CP = CV + R = 3 2R + R = 5 2R (one mole of a monatomic ideal gas) The heat capacity functions have a pivotal role in thermodynamics. We consider many of their properties further in the next section and in later chapters (particularly § 10-9 and § 10-10.) WebMay 13, 2024 · cp - cv = R. and we define the ratio of specific heats to be a number which we will call "gamma". gamma = cp / cv. If we divide the first equation by cp, and use the definition of "gamma" we obtain: R / cp = 1 - (1 / gamma) = (gamma - 1) / gamma. Now we use the equation we have derived for the entropy of a gas : crownsville maryland zip
