When two equal bulbs, one containing ammonia and the other nitrogen, are opened mouth-to-mouth to each other at room temperature, the entropy of the mixture of gases is likely to increase. Entropy is a measure of the disorder or randomness in a system. When the two gases are allowed to mix, they will spontaneously spread out to fill the entire space of the bulbs. This process of mixing increases the disorder of the system, and hence, the entropy increases. Ammonia and nitrogen are both gases at room temperature and they mix together easily because they are both nonpolar molecules. As a result, the entropy of the system will increase as the two gases mix together. Therefore, the correct answer is increase.
