Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

A room is divided by a barrier into two sections. One side of the room (state 1) has a volume of 1000 ft^3 and is initially at 70F, 50 psi and the other side of the barrier (state 2) has 200 lbm of air and is initially at 300F, 14.696 psi. The divider is removed and the air mixes until it reaches equilibrium (state 3). Find the final temperature and pressure of the room. You can assume removing the divider has a negligible effect on the air.
