Identify the process in which the entropy increases. the phase transition from a solid to a gas a decrease in the number of moles of a gas during a chemical reaction the phase transition from a liquid to a solid the phase transition from a gas to a liquid the phase transition from a gas to a solid

Answer 1

Answer:

The phase transition from a solid to a gas.

Explanation:

Entropy is related to the moles of gases available. The more gaseous moles, the higher the entropy.

Identify the process in which the entropy increases.

• the phase transition from a solid to a gas. YES. There are more gaseous moles available so entropy increases.
• a decrease in the number of moles of a gas during a chemical reaction. NO. This causes a decrease in entropy.
• the phase transition from a liquid to a solid. NO. There is almost no change in the entropy in this process.
• the phase transition from a gas to a liquid. NO. There is a decrease in entropy in this process.
• the phase transition from a gas to a solid. NO. There is a decrease in entropy in this process.
