Question

the diagram below shows four tubes with gas molecules floating in them. which tubes molecules have the greatest entropy?
a. i
b. ii
c. iii
d. iv

Explanation:

Step1: Understand the concept of entropy

Entropy is a measure of disorder or randomness in a system. For gas molecules in a container, a more disordered (randomly distributed) state has higher entropy.

Step2: Analyze each tube

• Tube I: Molecules are evenly distributed but not in the most random state (could be more spread out in terms of distribution pattern).
• Tube II: Molecules are clustered in parts, so less disordered (lower entropy).
• Tube III: Molecules are evenly distributed but similar to I in terms of randomness level.
• Tube IV: Molecules are spread out in a more random (less patterned) distribution compared to the others.

Answer:

D. IV
