Question

when compared at the same temperature, which of the following has the highest entropy?

c (graphite)
h2o(l)
c (diamond)
o2(g)
f2(l)

Explanation:

Analyze physical states

Entropy measures molecular disorder.
Gases have higher entropy than liquids.
Liquids have higher entropy than solids.

Compare the options

Identify the state of each substance:

• \(C\text{ (graphite)}\) is a solid.
• \(H_2O(l)\) is a liquid.
• \(C\text{ (diamond)}\) is a solid.
• \(O_2(g)\) is a gas.
• \(F_2(l)\) is a liquid.

Determine the highest entropy

The gaseous state has the highest disorder.
Therefore, \(O_2(g)\) has the highest entropy.

Answer:

• C (graphite)
• \(\text{H}_2\text{O}(l)\)
• C (diamond)
• \(\text{O}_2(g)\) (Correct answer)
• \(\text{F}_2(l)\)
