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
