Properties of a Gas
____________________ - a gas will completely fill any container it is in.
____________________ - gas particles, which are initially far apart can be crowded close together
____________________ - will be ~1/1000th the density of a solid or liquid phase
____________________ - gas particles glide easily past one another
____________________ - process of spreading out spontaneously to uniformly occupy a space
Illustrate and describe Effusion
Illustrate and describe Diffusion
Rate of Diffusion – depends on two main properties of the gas particles;
1) Size or mass of molecules 2) Temperature of molecules
Lighter and smaller gas particles will diffuse faster than heavier and larger particles.
_________________ molecules will diffuse faster than _________________ molecules.
Ideal Gas vs. Real Gas
Ideal gas - completely conforms to the Kinetic-Molecular theory
Real gas –
Ideal Gases
Real Gases
