gases Flashcards
pressure
the force per unit area on a surface
pressure formula
force/area
newton
the force that will increase the speed of one-kilogram mass by one meter per second each second that the force is applied
barometer
a device used to measure atmospheric pressure
partial pressure
the pressure of each gas in a mixture (P)
Dalton’s law of partial pressure
states that the law of the total pressure of a gas mixture is the sum of the partial pressures of the component gasses
vapor pressure
when water molecules exert a pressure
kinetic energy
the movement of the particles (atoms) with an object depend on energy
compressibility
a measure of how much the volume of matter decreases under pressure
volume
three-dimensional space inside the container holding the gas
temperature
the measurement of heat or how fast the particles are moving
STP
standard temperature & pressure
Boyle’s Law
law named for Charles Boyle, who studied the relationship between pressure, p, and volume, V, in the mid-1600s
Charles’ Law
law named for Jacques Charles, who studied the relationship volume, V and temperature, T around the turn of the 19th century
avogadro’s principle
equal volumes of gases contain equal numbers of moles
