Investigating Gay-Lussac's Law and Absolute Zero of Temperature with PocketLab and a Mason Jar

Rich ·
Gay-Lussac's Law states that when the volume of a container of gas is held constant, while the temperature of the gas is increased, then the pressure of the gas will also increase. In other words, pressure is directly proportional to the absolute temperature for a given mass of gas at constant volume. Although this is, strictly speaking, true only for an ideal gas, most gases that surround us behave much like an ideal gas. Even ordinary air, which is a mixture of gases, can behave like an...

Investigating Boyle's Law with PocketLab

Rich ·
With a pressure sensor built into PocketLab, there must surely be some way to investigate Boyle's Law. This law states that pressure and volume of an ideal gas are inversely proportional to one another provided that the temperature and amount of gas are kept constant within a closed system. What is needed is a closed system that is large enough to hold PocketLab in a way that pressure can be sensed while changing the volume of the enclosed gas (in our case, air).
