properties of gases definitions Flashcards
(8 cards)
matter
matter is a substance that has mass and occupies space (volume)
gas
a gas is defined as a substance with no well defined boundaries but diffuses rapidly to any container in which it is placed
pressure
pressure is force applied per unit area
P=F/A
boyle’s law
boyle’s law states that at constant temperature the volume of a fixed mass of gas is inversely proportional to the pressure
charle’s law
charle’s law states that at constant pressure the volume of a fixed mass of gas is directly proportional to temperature measured on the kelvin scale
gay-lussac’s law of combining volumes
gay-lussac’s law of combining volumes states that in a reaction between gases the volumes of the reacting gas and the volume of any gaseous product are in ratio of small whole numbers provided the volumes are measured at the same temperature and same pressure
avogadro’s law
avogadro’s law states that equal volumes of gases contain equal numbers of molecules provided the volumes are measured at the same temperature and pressure
ideal gas
an ideal gas is one which obeys all the assumptions of the kinetic theory of gases under all conditions of temperature and pressure
