Exploring Gas Laws
Once you have completed this activity, you should understand the concepts of:
-Kinetic molecular theory
Dalton’s Law of Partial Pressure
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.
Kinetic Molecular Theory:
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?_______________________________________________
