Questions & Step-by-Step Solutions
What happens to the entropy of a system when it undergoes an irreversible process?
Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Know the difference between reversible and irreversible processes. A reversible process can go back to its original state without any changes, while an irreversible process cannot.
Step 3: Recognize that during an irreversible process, energy is often dispersed or spread out, leading to more disorder.
Step 4: Conclude that because the disorder increases during an irreversible process, the entropy of the system must also increase.
Entropy – Entropy is a measure of the disorder or randomness in a system, and it tends to increase in irreversible processes.
Irreversible Processes – Irreversible processes are those that cannot be reversed without external influence, leading to an increase in entropy.
