Exploring Gas Laws Learning Goals: Once you have completed this activity, you should understand the concepts of: -Kinetic molecular theory - Dalton’s Law of Partial Pressure - Boyle’s Law - Charles’Law -Gay- Lussac’s Law In the boxes below, draw a diagram of what you think the gas particles would look like if you could zoom really close in to see them. Use ● for particles, → to show their movement. Bigger arrows mean more velocity. The box is the container. Low temperature High temperature high volume low volume High pressure Low pressure Kinetic Molecular Theory: Go to 1. Use the pump to put one pump of gas into the box. What happens to the clump of particles?_________________________________________________ (To answer the following questions, keep your eye on one particle and notice how it moves.)_ How do the particles move? (straight line, circular, random, etc.)_______________________________ Do the particles stay at a constant speed?______________ If not, what causes the speed to change?__________________________________________________ Do they always move in the same direction?_________________ If not, what causes their direction to change?_______________________________________________
