Question

Entropy is maximum in case of 

A) Steam

B) Water at 0° C 

C) Water at 4°C 

D) Ice

Answer 1

Answer: A) Steam

Explanation:

• Entropy is a term related to the thermodynamic system.

• In simple words, entropy can be defined as the random movement of the particle. 

• The random movement of the particles depends upon the shape and structure of the substance. 

• The more the size the more will be the random movement of the particles hence the entropy will be more. 

• It is low in solid and high in gases.

• So, in Ice due to the fixed rigid structure particles cannot move easily so its entropy is less.

 • In the Steam there is a large free space for the particles to move and hence they have high entropy amongst the given options.
