Entropy Change of Physical Processes?
a. mixing
b. condensing
c. dissolving
d. purification
e. sublimation
Answer:
entropy increase as a system becomes more disorder.
A mixing, two things are being put together, and mixed. So the system is more disorder, so it would increase
B. condensing, out of the system, one part is being removed. so the disorder is become less, so it would decrease
C. dissolving, the system becomes uniform, so the entropy wouldn't change at all.
D. purification the system becomes less disordered, so it would decrease.
E. sublimation the system changes from one phase to another, so the system doesn't change, nor does the entropy
mixing- two high concentration things become mixed to lower concentration. Entropy increases (more disorder)
condensing- vapor (high entropy) changes to liquid (low entropy) entropy decreases.
dissolving - same as mixing, until saturated, then no change in entropy.
purification - decrease in entropy
sublimation (conversion from solid to gas) - more ordered to disordered - entropy increases
