Answer: Option (C) is the correct answer.
Step-by-step explanation:
Entropy means the degree of randomness in a substance or object. This means more is the kinetic energy of particles of an object more will be its entropy.
For example, powdered sugar will have more number of particles and when it is added in a hot cup of coffee then its molecules will gain kinetic energy.
As a result, more number of collisions will take place due to which rate of reaction will also increase. Hence, powdered sugar will readily dissolve in the coffee.
Therefore, we can conclude that powdered sugar in a hot cup of coffee systems possesses the highest entropy.
