QuestionAnswer
kinetic molecular theory all matter made of small particles that have mass, for gases, distances between particles are very large, particles in constant random motion, all collisions between particles perfectly elastic. no loss of energy, temp determined by are of particles
measuring gas pressure barometer, manometer
barometer measure atmospheric pressure
manometer measures contained gas pressure
units of pressure atm, mmHg, kPa
conversions: 1atm is ? mmHg and ? kPa 760 mmHg 101.3 kPa
temperature average kinetic energy of the particles in a material
temp where all particle motion has stopped is called ? absolute zero= -273 degree C
____ is basis of Kelvin scale, In this scale size of each degree is the same as the size of a celsius degre absolute zero
STP T= 273K P= 1 atm
avogadros law 1 mol of any gas at stp is 22.4 L
Dalton's law at constant volume and temperature, total pressure exerted by a mixture of gases is = to the sume of the partial pressures of each gas P total= P1+P2+P3
Boyle's law PV (VaPor)
Charles' law TV (TeleVision Charlie Brown)
Gay-Lussac's Law P/T
avogadro's principle equal volume of gases contain equal numbers of moles v/n=k
Ideal Gas Law for an ideal gas pressure, vol, moles, and K temp of particles are all related PV=nRT
R= .0821
