Expert Solution

Step 1

Here are some points to easily identify the direction of change in entropy of physical processes-

Entropy is always assisted by the term "randomness" and "disorder". So, an increase in these two in any case will always be assisted with an increase in the entropy of the system,
So, from the above point, we can figure it out easily that, solid substances are more ordered and with least entropy, then comes liquid and at last the gases are the most disordered. So, on going from, solid>liquid then gas, entropy always increases,
Heating is always associated with an increase in entropy and cooling is associated with a decrease in entropy,
In general, spontaneous processes are associated with an increase in entropy of the system(though not always!) and the processes that involve any external force i.e. non-spontaneous processes are associated with decrease in entropy.
