KMT & other stuff
Ch 13 - 14
KMT is used to describe states of matter based on the energy and motion of the particles
No definite shape or volume
Weak intermolecular forces
Collisions are elastic – no energy is lost- it is transferred – total KE is constant at constant temperature
Takes Shape of Container
Diffusion – mixing due to molecular motion
Viscosity – resistance to flow
Surface tension – tendency of a liquid to maintain a minimum surface area (high intermolecular forces)
