First Law of Thermodynamics Concept Map Overview
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. It links a system's change in internal energy to the heat added to it and the work done by it. A concept map of the law starts with this energy balance and branches into the ideas that support it.
- Internal energy: the total microscopic kinetic and potential energy of a system
- Heat: energy transferred because of a temperature difference
- Work: energy transferred by a force moving through a distance, such as gas expansion
- Sign conventions: how positive and negative values for heat and work are recorded
- Applications: engines, refrigerators and chemical reactions that apply the energy balance
Use the map to revise the energy balance, check sign conventions and practice problems. CogniGuide can build a personalized version from your own notes.

First Law of Thermodynamics Questions
Common questions about the law and about building a map of it.
What is the equation for the first law of thermodynamics?
The change in internal energy equals heat added to the system minus work done by the system, written as ΔU = Q − W. Some textbooks write it as ΔU = Q + W when work is defined as work done on the system, so check your course's convention.
Why is the first law called conservation of energy?
It states that the total energy of an isolated system stays constant. Energy moves between forms such as heat and work, but the total amount does not change.
Which file types can I use to make the map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images. You can also type a topic instead.
Can I turn a thermodynamics map into a quiz?
Yes. Once the map is created, you can turn it into a quiz to test yourself. CogniGuide also has a free plan with 5 creations a week.
