Which of the following substances has the highest entropy? c. liquid water d. crushed ice

Usimov [2.4K]

Answer: liquid water

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

$\Delta S$ is positive when randomness increases and $\Delta S$ is negative when randomness decreases.

Gases have more entropy than liquids and liquids have more entropy than solids due to movement of particles.

Thus liquid water will have more entropy than crushed ice.
