Dispersal of matter and energy can be directly related to spontaneity if the: Select the correct answer below a. change in internal energy is positive

b. change in internal energy is negative

c. change in internal energy is zero

d. there are no conditions for this correlation

C. change in internal energy is zero

Explanation:

Let's say we have a scenario of an ideal gas which is in a system that is isolated, and which is filled inside a flask that is connected to another flask and separated by a valve. If this valve gets to be opened, the gas is going to spontaneously fill the other flask through expansion.

Then we would have

work done , W = -P∆V = 0.

With vacuum, P equal 0.

Since there is a complete isolation of this system, we would have bit that no heat exchange is happening.

Q = 0

Using the first law of thermodynamics,

∆U= Q + W = 0

Therefore we conclude that the change in internal energy is zero
