 * Common misconceptions:**
 * There are atoms or other particles in the 'empty space' between gas molecules.
 * Particles do not slow down when a gas is cooled.
 * Gases weigh less than liquids.
 * The bubbles produced in boiling water are made of oxygen.


 * Interesting facts:**
 * Gas particles are spread out, and between them is empty space.
 * Particles in a liquid move slower than in a gases, and particles in a solid move slower than those in a liquid.
 * The same amount of a substance, will weigh the same, regardless of what state they are in.
 * When water boils, it goes from liquid to gas - so the bubbles are steam.
 * Collisions between gas particles are elastic, energy is conserved. Kinetic energy can be transferred from one particle to another, but the total kinetic energy will remain constant.
 * The average kinetic energy of particles increases as the temperature of the gas is increased.
 * The rate that gases diffuse depends on the average velocity of their particles.
