The Ideal Gas Law: Crash Course Chemistry #12
CrashCourse・9 minutes read
Gas is all around us, with Boyle's Law linking pressure and volume in a closed system based on experiments by Henry Power and Richard Towneley. The Ideal Gas Law, developed by Jacques Charles and Amedeo Avogadro, explains the relationship between pressure, volume, temperature, and the number of moles of a gas in real-life scenarios.
Insights
- Boyle's Law, often credited to Robert Boyle, was primarily based on experiments conducted by Henry Power and Richard Towneley, highlighting the collaborative nature of scientific discoveries and the contributions of lesser-known figures in shaping fundamental principles.
- The Ideal Gas Law, formulated by Jacques Charles and Amedeo Avogadro, encompasses pressure, volume, temperature, number of moles, and the Universal Gas Constant, offering a comprehensive framework to understand the behavior of gases in various conditions and scenarios.

Gas Laws: The Science of Gases Explained
- Gas is all around us, present in space, on Mars, dissolved in blood and soda, creating an ocean of gas that we are constantly submerged in.
- The behavior of gases can be described theoretically, experimentally, and mathematically, with Boyle's Law being a significant discovery linking pressure and volume in a closed system.
- Boyle's Law, attributed to Robert Boyle, was actually based on experiments largely conducted by Henry Power, a working-class scientist, and Richard Towneley, a less wealthy Englishman.
- The Ideal Gas Law, PV=nRT, was developed by Jacques Charles and Amedeo Avogadro, showing the relationship between pressure, volume, temperature, and the number of moles of a gas.
- Pressure, volume, number of moles, the Universal Gas Constant (R), and temperature are the key components of the Ideal Gas Law, with temperature representing kinetic energy at the atomic level.
- The Ideal Gas Law can be used to explain real-life scenarios, such as the crushing of a soda can when exposed to ice water, showcasing how changes in temperature and number of moles affect pressure and volume.
- STP (standard temperature and pressure), the volume of one mole of an ideal gas at STP (22.4 liters), and absolute zero (-273.15 degrees Celsius) are essential concepts related to gases and the Ideal Gas Law.
