chemistry quiz 1 11b term 1

compressibility

the measure of how much volume decreases under pressure

kinetic theory

explains that gases r more easily compressible than liquids nd solids cz gas particles r spaced apart

volume of 1 gas particle is smaller than overall gas volume

factors that affect compressibility

temperature ( K, C° > K = C° + 273 )

pressure ( kPa )

volume ( L )

moles

what happens if the pressure increases

particles get closer tgth ( volume decreases )

what happens if the pressure decreases

the particles become more spaced apart ( volume increases )

boyles law

if temperature is constant, pressure and volume are inversely proportional

boyles law formula

P1V1 = P2V2

charles law

if pressure is constant, temperature and volume are directly proportional

charles law formula

V1/T1 = V2/T2 or V1T2 = V2T1

gay lussacs law

if volume is constant, temperature and pressure are directly proportional

gay lussacs law formula

P1/T1 = P2/T2 or P1T2 = P2T1

combined gas law

combines all 3 gas laws

combined gas law formula

P1 x V1 / T1 = P2 x V2 / T2

OR

T2 ( P1 x V1 ) = T1 ( P2 x V2 )

standard temp? ( stp )

273 K

stantard pressure ? ( stp )

101.3 atm

avogadros law

the volume of a gas is directly proportional to the number of moles of gas present

avogadros law formula

V1/N1 = V2/N2
