FAQ
Frequently Asked Questions
Not exactly. Charles's law relates volume and temperature at constant pressure. The pressure-temperature relationship at constant volume is often *called* Charles's law in some regions, but it is historically Gay-Lussac's law. In many textbooks, they are distinguished.
Temperature must be in an absolute scale (Kelvin), and pressure can be in any consistent unit (pascals, atmospheres, etc.), as long as the proportionality is maintained.
Joseph-Louis Gay-Lussac was a French chemist and physicist who published this law relating the pressure and temperature of a gas in 1808.
It is fundamental in engineering fields dealing with pressurized gases, such as in designing scuba tanks, aerosol cans, and internal combustion engines, where temperature changes can lead to dangerous pressure changes.
A fundamental gas law stating that the pressure of a given mass of gas is directly proportional to its absolute temperature when its volume is held constant.
Gay-lussac's law is usually academic / scientific / technical in register.
