I have always liked the Charles’ Law experiment (Experiment-17 in the Chem 30A lab manual), and we will look at some data together in class. Since volume and temperature are directly proportional, we can measure temperature by watching a sample of gas expand and contract (assuming the pressure is NOT changing), and these observations lead us directly to the absolute temperature scale.
Since we’re doing all our laboratory “experiments” virtually, we can do more complicated experiments, right? So, let’s jump into Beyond Labz and tackle the big three gas laws: Avogadro’s Law, Boyle’s Law, and Charles’ Law. The ABCs, as it were:
A) Volume is proportional to the number of gas particles: V/n = constant
B) Pressure and volume are inversely proportional: PV = constant
C) Volume is proportional to temperature: V/T = constant
Combining these three laws, we get the Ideal Gas Law: PV = nRT
Note: pressure is directly proportional to temperature: P/T = constant; this relationship is known as the Gay-Lussac Law.
We can test relationships A, B, and C in Beyond Labz by observing an imaginary balloon. Use this worksheet
