a : accounts for intermolecular attractionsb : accounts for molecular volumen^2a/V^2 : adjusts predicted press upnb : adjust predicted volume down
which statement describes the particles in a sample comprise a mixture of gases in ~ a provide temperature? choose all that apply-all the particles have actually the same typical kinetic energy-on average, the lighter corpuscle move quicker than the more heavier particles-all the particles have the very same mass-all the particles have actually the same most probable speed
-all the particles have the same mean kinetic energy-on average, the lighter corpuscle move much faster than the more heavier particles
arrange the following gas molecules in order of diminish diffusion ratesmethane, fluorine, neon, helium
which explain correctly defines what happens once a gas is cook at consistent pressure? assume the the container is not rigid. Select all that apply.-the gas rises in volume b/c the particles increase in size-the volume of the gas sample will increase-the gas particles relocate faster-the surface area the the wall surfaces of the container decreases-the gas corpuscle collide through the wall surfaces of the container with a greater force
-the volume the the gas sample will increase-the gas particles relocate faster-the gas particles collide through the walls of the container through a greater force
as temperature the a gas increases ______. Choose all the apply-the speed of individual gas particles increases yet the median speed remains the same-the median kinetic energy of the gas corpuscle increase-the median speed the a gas bit increases-the circulation of the speed of the light particles narrows
-the mean kinetic power of the gas particles increase-the typical speed the a gas bit increases

the van der waals equation is a modified version of the ____ gas equation that takes right into account both the ________ forces between gas particles and the actual molecular ______ that the gas particles
at STP, the density of argon is _____-ten time the density of neon-one fifty percent the thickness of neon-twice the density of neon-the very same as the density of neon
which the the complying with statements correctly explain effusion and also diffusion? select all the apply-diffusion and effusion room the exact same processes-the rate of effusion is the very same as the price of diffusion for a provided substance-lower molar fixed gas corpuscle effuse and also diffuse faster since the u(ms) is higher-the effusion rate is proportional come the thickness of the gas-both the effusion rate and the diffusion rate are inversely proportional come the square source of the molar mass of the gas
-lower molar fixed gas corpuscle effuse and also diffuse faster because the u(ms) is higher-both the effusion rate and the diffusion rate are inversely proportional to the square source of the molar massive of the gas
