What are each of the following observations an example of? Drag the appropriate items to their respective bins. If the tightly packed food is placed in the kitchen for a long time then you can smell the gas as it penetrates through the small holes in the plastic. Diffusion A balloon in a constant environment gets smaller and smaller over the course of a week as gas leaks through small holes in the rubber. When person applies perfume in one corner of the room you can smell its fragrance in another room. Effusion When a coworker microwaves popcorn, you can smell the vapors in your office 5 minutes later.

Learning Goal: To understand some aspects of molecular motion in the gas phase. The kinetic molecular theory of gases explains how gas molecules behave in terms of motion, speed, and energy. One important aspect of this theory deals with the relationship between temperature and the average speed of the gas molecules. Increasing the temperature of a gas sample increases the average kinetic energy of the molecules. The kinetic energy of a molecule determines its speed. It is important to realize that not all molecules in a sample will have the same kinetic energy, which is why we refer to the average kinetic energy and the average speed. The speed of a particle with average kinetic energy is called the root mean square (rms) speed, Urms. The rms speed may be expressed by the following equation: Urms 3RT M where R is the ideal gas constant, T is the absolute temperature, and M is the molar mass of the substance in kilograms per mole. The constant motion of gas molecules causes diffusion and effusion. Diffusion is the gradual mixing of two substances resulting from the movement of their particles. Effusion is the gradual escape of gas molecules through microscopic holes in their container.
