Thermodynamic Processes and Work

Start with the processes

The Thermodynamic Processes mind map is a useful starting point for comparing processes. It sets out isochoric, isobaric and isothermal cases alongside relationships involving pressure, volume, temperature, heat and work. For example, its isochoric section shows constant volume and zero work.

The Thermal Processes mind map offers another way to review the terms. It includes adiabatic processes as well as constant-volume, constant-pressure and constant-temperature processes. Use it to look at how pressure, volume and temperature are presented for each case.

Practice with quizzes and flashcards

After looking at a map, try Basic Thermo. Its questions include the meanings of isobaric and isochoric processes. You can return to the maps to compare the terms before trying the questions again.

The quiz on energy transformations, efficiency and pressure-volume diagrams asks about process types and the area inside a closed cycle on a pressure-volume diagram. The Sign Conventions flashcards focus on heat and work going into and out of a system. Use them to practice the sign conventions presented in the deck.

Explore work in more detail

A mind map on mechanical forms of work includes work done by a constant force and work involving torque. Another map covers moving boundary work, including the expansion or compression of a gas in a piston-cylinder device and its representation on a pressure-volume diagram.

These resources offer different ways into Thermodynamic Processes and Work, a section of the Thermodynamics unit in Physics. The process maps help you identify the conditions being described; the work maps and quiz let you look more closely at how work appears in the listed examples.

Choose a resource that fits what you are studying, and use a map alongside a quiz as you work through the topic.
