Really quick question about entropy

[proton]

My question may be kind of a dumb question, but I tried searching for the explanation online and in my crappy textbook and my lecture notes are kinda unclear.

Consider 2 systems, A and B, that are brought into contact with each other, with accessible states W_A and W_B, respectively. After contact, the combined system then has (W_A)(W_B). Now, is this true for equilibrium and/or nonequilibrium?

My guess is that its at nonequilibrium because the net entropy must remain the same or increase, which leads to the 2nd law of thermodynamics

you actually may try the zeorth law of themodynamics whichstates that if a system a is i themal equilibrium with a system b and system b is in thermal equi. with system c then and c are also in thermal equi.
i may have ans. your ques. wrong as it is unclesr to me

present quesstion in clear way

in above sentences your confused me atAfter contact, the combined system then has (W_A)(W_B). in physics you must represent question in clear way to proper understading OK

Ok, after systems A and B are brought into contact, the total number of microstates in the combined system consisting of systems A and B, is equal to (W_A)*(W_B)
