This applet runs automatically. You can change the width of the container by clicking at its right side and dragging left or right. You can change the total number of molecules, the speed of the molecules and the pressure. The volume changes automatically. Positioning the mass over the container and pressing the mouse button suspends the motion of the molecules and shows the direction of their velocities.
Motion resumes when the mouse is released.
This Java applet simulates a microscopic model for an ideal gas. As discussed in sections 12.4 and 12.5, a gas is considered ideal when there is no interaction between the molecules and when collisions between the the molecules and the container walls are elastic. The behavior of the molecules is described by equation 12.6b. Fu-Kwun Hwang Go to the web site and link to the Online Library for further information.
