Question | Answer |
diffusion | spontaneous mixing of the particles of two substances caused by their random motion |
effusion | a process by which gas partially pass through a tiny opening |
elastic collision | a collision between gas particles and between gas particles and container walls in which there is no net loss of kinetic energy |
fluid | a substance that can flow and therefore take the shape of its container; a liquid or gas |
ideal gas | an imaginary gas that perfectly fits the assumptions of the kinetic-molecular theory |
kinetic-molecular theory | a theory based on the idea that particles of matter are always in motion |
real gas | a gas that does not behave completely according to the assumption of the kinetic molecular theory |
atmosphere of pressure (atm) | exactly equivalent |
barometer | a device used to measure atmospheric pressure |
millimeter of mercury (mm of Hg) | a common unit of pressure |
newton | the SI unit for force; the force that will increase the speed of a one kilogram mass by one merer per second |
pascal | the pressure exerted by a force of one newton acting on an area of one square meter |
kilopascal | is a unit for measureing pressure |
pressure | the force per unit area of a surface |
standard temperature and pressure (STP) | the agreed upon standard conditions of exactly 1 atm pressure and 0 C |
standard ambient temperature and pressure (SATP) | corresponds to 25C, 1 bar |
torr | non-SI unit with the ratio of 760 to 1 standard atmosphere |
absolute zero | the temperature -273.15 C, given a value of zero in the kelvin scale |
Kelvin | temperature scale used in chemistry and physics |
Boyle’s Law | the volume of a fixed mass of gas varies inversely with pressure at a constant temperature |
Charles’s Law | the volume of a fixed amount of gas at a constant pressure varies directly with the Kelvin temperature |
Combined gas law | the relationship between the pressure,volume, and temperature of a fixed amount of a gas |
Dalton’s Law of partial pressure | the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases |
Gay-Lusscac’s Law | the pressure of a fixed mass of gas at a constant volume varies directly with the kelvin temperature |
Ideal gas law | an imaginary gas that perfectly fits all the assumptions of the kinetic-molecular theory |
Partial pressure | the pressure of each gas in a mixture |
Avogadro’s Law | equal volumes if gases at the same temperature and pressure contain equal numbers of molecules |
van der Waals equation | An equation of state that relates the pressure, volume, and absolute temperature of a gas taking into account the finite size of molecules, and their intermolecular attraction |
bar | a unit of pressure equal to 100 kilopascals |
Gas Constant | a constant, equal to 8.314 joules per Kelvin or 1.985 calories per degree Celsius, that is the constant proportionality in equation Pressure x Volume is n x R x Temperature, relating the pressure and volume of a quantity of gas to the absolute temperature |
