"The laws describing the behaviour of gases under fixed pressure, volume and absolute temperature conditions are called Gas Laws."
Understanding how to work with gases, gas laws and their applications, including ideal gas equation, Dalton's law of partial pressure, and the gas constant.
"The basic gas laws were discovered by the end of the 18th century..."
"...relationships between pressure, volume and temperature of a sample of gas could be obtained..."
"...which would hold to approximation for all gases."
"These macroscopic gas laws were found to be consistent with atomic and kinetic theory."
