PV Diagrams

What is a PV diagram?

• A PV diagram is a graphical representation of the temperature-volume relationship of a system.

• A PV diagram is a tool used to measure the pressure and volume of a system simultaneously.

• A PV diagram is a mathematical equation that describes the pressure-volume relationship of a system.

• A PV diagram is a graphical representation of the pressure-volume relationship of a system.

How can PV diagrams be interpreted?

• PV diagrams show the relationship between pressure and temperature in a thermodynamic system.

• PV diagrams show the relationship between pressure and volume in a thermodynamic system.
