Consider a system consisting of two Einstein solids P and Q in thermal contact. Assume that we know the number of atoms in each solid and ?. What do we know about the system if we also know the quantum state of each atom in each solid?
A. Its macrostate
B. Its microstate
C. Its macropartition
D. Its microstate and macropartition
E. Its macrostate and macropartition
F. Its macrostate and microstate
T. Its macrostate, microstate, and macropartition

If we know the quantum state of each atom in each solid, we know the microstate of the system. The macrostate can be determined from the microstate, as it is a higher-level description of the system's properties.
