Chapter 6, Problem 6.24CU

Consider the PV diagram shown. The diagram shows an ideal gas which starts in state 1 and is taken to state 2 along the depicted path. (The number of moles of the gas is constant in process) A) which statement characterizes the work done during the process and why? 1. Energy enters the gas due to work 2. Energy leaves the gas due to work 3. No energy enters or leaves the gas due to work 4. Not enough information to tell B) is the change in the internal energy of the gas during the process… and why? 1. Positive 2. Negative 3. Zero 4. Not enough information to tell C) which statement characterizes the heat transfer during the process? 1. Energy enters the gas due to heat transfer 2. Energy leaves the gas due to heat transfer 3. No energy enters or leaves the gas to to heat transfer 4. Not enough information to tell

1. Methane gas (CH4) behaves like an ideal gas with y = 1.306. Determine the molar heat capacity at constant volume, C, and the molar heat capacity at constant pressure, Cp.
