Respond to the questions and prompts in the orange boxes. Vocabulary: absolute zero, controlled experiment, diffusion, dynamic equilibrium, Kelvin scale, kinetic energy Prior Knowledge Question (Do this BEFORE using the Gizmo.) Have you ever smelled microwave popcorn? The oddly enticing scent can fill a whole house. How do you think the smell of popcorn spreads through the air? I think the smell of popcorn spreads because the odor molecule spread into the air. Gizmo Warm-up Smells are carried by tiny particles that move through the air. The Diffusion Gizmo shows gas particles in a chamber that is divided into two regions by a partial wall. Click Play ( ) and observe. 1. Describe the motion of the gas particles. The particles in a gas are moving very quickly in random directions. 2. Over time, what is happening? over time they evenly distributed throughout the volume of the container. When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. This process, in which particles move from an area of high concentration (region A) to an area of low concentration (region B), is called diffusion.
