One mole of which of the following has the highest entropy?

Options

  1. ALiquid nitrogen
  2. BHydrogen gas
  3. CMercury
  4. DDiamond

Correct answer

B. Hydrogen gas

Step-by-step solution

Entropy is the measure of degree of disorder (or randomness) of a system. The greater the disorder in a system, the higher is the entropy. Hence, entropy is highest for hydrogen gas.
