Day 89: Section 12.2 Terms

standard temperature and pressure (STP)

a temperature and pressure agreed upon by chemists for comparison of research; 0 °C (273.15 K) and 101.325 kPa

Kelvin scale

an absolute temperature scale with 100 kelvins between the normal boiling point (373.15 K) and freezing point (273.15 K) of water

Gay-Lussac's law

the law that states that the Kelvin temperature and pressure of a sample of gas at a constant volume are directly related; P/T = k

Charles's law

the law that states that the Kelvin temperature and volume of a sample of gas at a constant pressure are directly related; V/T = k

Boyle's law

the law that states that the pressure and volume of a sample of gas at a constant temperature are inversely related; PV = k

combined gas law

the law that states that the pressure, volume, and Kelvin temperature of a sample of a gas vary jointly; PV/T = k

Dalton's law of partial pressures

the law that states that the total pressure of a mixture of gases equals the sum of the pressures of each individual gas, called the partial pressures
