Understanding PV Diagrams and Concepts

The video tutorial explains PV diagrams used in physics, focusing on ideal gases. It describes how pressure and volume are plotted on the axes and how changes in these variables are represented by arrows. The tutorial also covers how temperature is inferred from PV diagrams, using isotherms to show constant temperature curves. The relationship between pressure, volume, and temperature in ideal gases is highlighted, providing a foundational understanding of PV diagrams.

What does the vertical axis represent in a PV diagram?
