Question

Which of the following changes in the state of a substance results in an increase in the entropy? Gas to solid Gas to liquid Liquid to solid Solid to liquid

Answer 1

Answer:

Solid to liquid

Explanation:

Entropy is a state of randomness or disorderliness of the particles of a system. Some part of the heat energy of a system is related to the state of disorder or randomness of the particles of the system.

The entropic level of a system depends on two of major factors:

1. Temperature: Entropy increases with temperature rise due to the fact that the randomness of the particles of a system increases at a higher temperature.

2. Physical state of matter: The increasing order of entropy is:

Solid < Liquid < Gas

Gases are the most disordered and have the highest entropy. In moving from solid to liquid to gas, entropy of a system would increase.
