Answer:
condensation of water vapor to form dew
Step-by-step explanation:
Entropy is generally defined as degree of randomness. More the randomness in a system more its entropy.
If a system goes from a more random state to less random state then its entropy is said to be decreased.
In a physical process when the following leads to decrease in entropy
a) change from gas to liquid
b) change from gas to solid
c) change from liquid to solid
Increase in entropy:
a) change form solid to liquid
b) Change from solid to gas.
c) change from liquid to gas.
In the given examples condensation of water vapor to dew is is the change of gas to liquid thus the entropy will decrease.
