Chapters 10-11 WebLab#1 “The One-Atom Ideal Gas” * Go to the following website: http://galileoandeinstein.physics.virginia.edu/more_stuff/Applets/Piston/jarapplet.html * Carefully read the instructions. * Observe the motion of the gas atom. Note the velocity of the atom and the pressure, volume, and temperature of the gas. * Select the “Compress” button to make the piston move downward. Observe how the velocity, pressure, volume, and temperature change. Questions: 1) What happens to the speed of the atom as the piston moves? In terms of physics, why does this happen? 2) What happens to the pressure of the gas as the piston moves?

Unformatted text preview: In terms of physics, why does this happen? What happens to the temperature of the gas as the piston moves? In terms of physics, why does this happen? 3) What happens to the temperature of the gas as the piston moves? 4) Neglect gravity. Does the piston want to fall? What must happen for the piston to move? 5) Imagine you heated the gas. a) How would the motion of the atom change? b) If the piston is locked in place, what happens to the pressure of the gas? Why? c) If the piston is free to move, what will it do? Why? d) Can heat do work? Explain....
