Two flasks are connected by a closed valve. One contains gas particles and the other contains a vacuum. If the valve is opened such that the particles move until they fill both flasks, the process by which the particles can reconvene entirely in one of the flasks is: Select the correct answer below: a. spontaneous
b. nonspontaneous
c. exergonic
d. endothermic

b. nonspontaneous .

Explanation:

Hello there!

In this case, by considering the given description, it is possible for us to realize this process is b. nonspontaneous  because the molecules of the gas are going to tend to spread all around the flasks instead of convening together unless an external force was applied. In such a way, this cannot be spontaneous as it will occur without any external action, and the concepts of exergonic and endothermic are specifically for chemical reactions.
