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​.
