Chapter 11 Flashcards
The force per unit area on a surface
Pressure
The force that will increase the speed of a one-kilogram mass by one meter per second each second that the force is applied
Newton
A device used to measure atmospheric pressure
Barometer
A common unit of pressure, symbolized by mm Hg
Millimeters of mercury
A unit of pressure equivalent to 760 mm Hg, symbolized by atm
Atmosphere of pressure
The pressure exerted by a force of one newton acting on an area of one square meter
Pascal
The pressure of each gas in a mixture
Partial pressure
States that the total pressure of a gas mixture is the sum of the partial pressures of the component gases (Pt= P1+P2 …)
Dalton’s Law of Partial Pressures
States the the volume of a fixed mass of gas varies inversely with the pressure at constant temperature (PV = k)
Boyle’s Law
The temperature of -273.15 degrees Celsius or 0 degrees Kelvin
Absolute zero
States that the volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature (V=kT)
Charles’ Law
States that the pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature (P=kT)
Gay-Lussac’s Law
Expresses the relationship between pressure, volume, and temperature of a fixed amount of gas (PV / T = k)
Combined gas law
States that at constant temperature and pressure, the volumes of gaseous reactants and products and be expressed as ratios of small whole numbers
Gay-Lussac’s Law of Combining Volumes of Gases
States that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules (V=kn)
Avogadro’s Law
