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 : WebHeat causes air in the bottle to expand. As the air requires more space, it flows into the balloon and inflates it.
