Relationship between molecular speed and mass with uniform temperature Attribution Teaching JPEG	The randomized, or thermal, energy of particles such as atoms and molecules gives a substance its temperature. For ideal monatomic gases this means kinetic energy from translations. Here, the size of helium atoms relative to their spacing is shown to scale under 136 atmospheres of pressure. These room-temperature atoms have a certain, average speed (slowed down here two trillion fold). At any given instant however, a particular helium atom may be moving much faster than average while another may be nearly motionless. Five atoms are colored red to facilitate following their motions. Attribution Teaching JPEG	Plot of various quantities near the critical temperature for an ideal Bose-Einstein gas Attribution Teaching JPEG
Thermally agitated polypeptide Attribution Teaching JPEG	Probability density functions of the molecular speed for four noble gases at a temperature of 298.15 K (25 °C). The four gases are helium (4He), neon (20Ne), argon (40Ar) and xenon (132Xe); the superscripts indicate their mass numbers. These probability density functions have dimensions of probability times inverse speed; since probability is dimensionless, they can be expressed in units of seconds per meter. Attribution Teaching JPEG	Atoms in a crystal can vibrate about their equilibrium positions in the lattice. Such vibrations account largely for the heat capacity of crystalline dielectrics; with metals, electrons also contribute to the heat capacity. Attribution Teaching JPEG

Great for teachers!
Building slideshows as layers in a free graphics program such as GIMP or Seashore is an inexpensive and compelling way to bring these images into the classroom. Teachers might consider using the inexpensive LaPazz WP5540-TAB1Q graphics tablet from WikiPremed (only $34.95) for this purpose. WikiPremed believes that presenting teaching slides using a paint program such as Photoshop, GIMP or Seashore with a graphics tablet is much better than Keynote or Powerpoint because the writing and drawing capabilities are much better. It's how we do it!
