Problem 1 N molecules of carbon dioxide gas Co, (considered as an ideal gas) undergo the cycle shown in the P-V diagram on the right. As a reminder, a CO, molecule has all atoms on a line. Assume that all processes are quasistatic and that the temperature remains such that rotational degrees of freedom are activated, but vibrational degrees of freedom are frozen out. Capital letters A, B, C represent the states at the corners of the cycle, while lowercase...
