|
pressure
|
the amount of force exerted per unit area of surface
|
|
|
Newton
|
the SI unit for force; the force that will increase the speed of a 1kg mass by a m/s each second that the forces is applied (N)
|
|
|
Pascal
|
the SI unit of pressure; equal to the force of 1N exerted over an are of 1m^2 (Pa)
|
|
|
standard temperature and pressure
|
for a gas the temperature of 0 degrees Celsius and the pressure 1.00 atmosphere
|
|
|
Kinetic- molecular theory
|
a theory that explains that the behavior of physical systems depends on the combined actions of the molecules constituting the system.
|
|
|
Boyle's Law
|
the law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as the temperature the volume of the gas increases as the pressure of the gas decreases as the pressure of the gas increases.
|
|
|
Charles Law
|
the law that states that for a fixed amount of gas at a constant pressure, the volume of that gas increases as temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases
|
|
|
Gay- Lussac Law
|
the law that states that the pressure of a gas at a constant volume is directly proportional to the absolute temperature
|
|
|
Avogadros Law
|
the law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
|
|
|
ideal gas
|
an imaginary gas whose particles are infinitely small and do not interact with each other
|
|
|
ideal gas law
|
the law that states the mathematical relationship of pressure, volume, temperature, the gas constant and the number of moles of a gas
|
|
|
diffusion
|
the passage of a gas under pressure through a tiny opening
|
|
|
Graham's Law
|
the law that states that the rate of diffusion of a gas is inversely proportional to the square root of the gas's density
|
|
|
Gay- Lussacs law of combining volumes
|
the law that states that the volumes of gases involved in a chemical change can be represented by the ratio of small whole numbers
|
|
|
partial pressure
|
the pressure of each gas in a mixture
|
|
|
Dalton's law of partial pressure
|
the law that states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.
