The Gas Law Is One Ratio
You'll learnwhy every gas-law temperature has to be in kelvin, how one full ratio replaces every two-variable rule, and what the ideal gas model actually assumes.
A sealed can reads 300 kPa in a 20 degree room. Carry it into a 40 degree car: has the pressure doubled? The gas says no, and the reason is the temperature scale. Twelve short steps; press Next for each one.
one sealed can, one piston · every temperature converted to kelvin first
Before you start
What you're looking at
A sealed can of gas with a pressure gauge, and later the same gas behind a piston that can slide.
The question
What does the gauge read when the can warms up, and which temperature scale is the gas law written in?
