درشت-استات، درشت-حالت dorošt-estât, dorošt-hâlat
*Fr.: macro-état*
*Statistical physics*: A state of a physical system that is described in
terms of the system's overall or average properties at a macroscopic
level (→ *temperature*,
→ *pressure*,
→ *density*,
→ *internal energy*, etc.).
A macrostate will generally consist of many different
→ *microstate*s. In defining a macrostate we ignore what is
going on at the microscopic (atomic/molecular) level.
The → *probability*
of a certain macrostate is determined by how many
microstates correspond to this macrostate. Therefore, the greater the number of microstates
which lead to a particular macrostate, the greater the probability of observing that
macrostate. Same as → *macroscopic state*.
