# Question

An ideal gas initially at temperature To, pressure po, and volume Vo is compressed to one-half its initial volume. As shown in Fig. 12.20, process 1 is adiabatic, 2 is isothermal, and 3 is isobaric. Rank the work done on the gas and the final temperatures of the gas, from highest to lowest, for all three processes, and explain how you decided upon your rankings.
