Physics: Internal Energy and Work
by Texas Instruments - Simulation Lesson


  • Students will observe how the relationship between a change in volume and the work that is done.
  • Students will relate this information to a graph with a slope equal to the pressure of the system.
  • Student will develop the equation for amount of work done when compressing a gas.
  • Students will calculate the heat loss from the internal energy equation and the work done.

About the Lesson

This lesson allows students to develop the equation for work by observing the relationship between volume change and work done in a cylinder and piston at constant pressure.
As a result, students will:

  • Understand how to calculate work done.
  • Measure work needed to change volume.
  • Calculate heat loss given the total energy of a system.
