Internal Energy and Work

Published on 07/16/2011

Activity Overview

In this lesson, students will develop the equation for work by observing the relationship between volume change and work done in a cylinder and piston at constant pressure.

Objectives

  • 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.

Vocabulary

  • heatv
  • height
  • internal energy
  • pressure
  • radius
  • volume
  • work

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.
