Gas Laws and Titrations Quiz Flashcards
what are the properties of gases
compressible, expand as temperature increases, flow very easily, have low density, miscible
whats the kinetic molecular theory state
- gases composed of tiny particles that are in constant motions
- particles move in straight lines until they collide with another particle or the walls of a container
- collisions between particles are elastic
- average kinetic energy of particles is directly proportional to temperature of the gas
- particles in a gas are assumed to have a negligible volume
- no intermolecular f9rces between gas particles
behaviours of an ideal gas
gas molecules are in constant random motion, moleculs are point masses (have mass but dont take up space), do not have attractive or repulsive forces acting on each other (interact only through perfect elastic collisons)
point mass
when the volume of the container is much greater than the volume of the gas itself, causing it to have a overall volume of 0 meaning that the gas volumes have a mass but dont take up any space
elastic collision
molecules exchange energy without friction and the total kinetic energy stays constant throughout all molelcules
what are the theoretical properties of an ideal gas
volume is negligble, there are no forces of attraction between molecules, no energy lost in molecular collisions
boyles law
aspressure on a gas incr3ease, volume of gas decreases inversely
charles law
as temprature of gas increases, the volume increases proportionally
gay lussacs law
as temperature of gas increases, the pressure increases proportionally
combined gas law
the product of pressure and volume of a gas sample is propritonal to its absolute temeprature in kelvin
law of ocmbining volumes
when measure at the same temperature and pressure, volumes of gaseous reactants and products of chemical reactions are always in simple ratios of whole numbers
avagadros theory
equal volumes of gas at the same pressure nd temperture contain equal numbers of molecules
what does KMT explain
behaviours of an ideal gas
behavioural difference between real gas and ideal gas
real gases occupy space and have moecluar interactions where as ideal gases dont
how to get ideal behaviour
high temperatures, low pressures, lowest mass possible, no HB or DD, lowest amount of LDF possible
