Learning Objectives

• Calculate the work done during a process with an ideal gas using either the appropriate derived equation or using the area under the curve on a PV diagram.
• Calculate the change in energy for any thermodynamic process.
• Use the First Law of Thermodynamics to solve for the energy transferred as heat during a thermodynamic process.
• Interpret a PV diagram to determine the sign of the energy transfers as an ideal gas moves from one state to another.
