Chem matters and materials p2 Flashcards
elastic (collision)
total kinetic energy before and after a collision is constant
pressure (p)
the force that acts per unit of surface area
volume (V)
the amount of space a gas occupies at a certain temperature and pressure
temperature (T)
a measure of the average kinetic energy of the molecules
moles (n)
a measure of the amount of gas in the container
ideal gas
a theoretical gas which obeys the gas laws under all conditions of temperature and pressure
Boyle’s law
the volume of a fixed amount of gas is inversely proportional the the pressure at a constant temperature
Boyle’s law in symbols
V ∝ 1/p
Avogadro’s law
the volume of gas (V) is directly proportional to the number of moles (n)of a gas at a constant temperature
Avogadro’s law in symbols
V ∝ n
ideal gas law
an amount of gas is determined by its pressure, volume and temperature
ideal gas law in symbols
pV = nRT
