Spontaneous Processes & the Dispersal of Matter and Energy
Dispersal of Matter
An isolated system consists of an ideal gas in one flask that is connected by a closed valve to a second flask containing a vacuum. Once the valve is opened, the gas spontaneously becomes evenly distributed between the flasks.
Dispersal of Energy
When two objects at different temperatures come in contact, heat spontaneously flows from the hotter to the colder object.
Macro-states & Micro-states
There are only 5 kinds of possibilities for the four particle system. These possibilities are called macro-states.
For 3 of the 5 macro-states of the four particle system, there are further possible arrangements of the particles.
These possibilities are called micro-states.
