Questions & Step-by-Step Solutions
In an irreversible process, the change in entropy of the universe is:
Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Know that the universe is made up of all systems and their surroundings.
Step 3: Recognize that processes can be reversible or irreversible. Irreversible processes cannot return to their original state without external influence.
Step 4: Learn that in an irreversible process, energy is dispersed and systems become more disordered.
Step 5: Realize that when disorder increases, the entropy of the system increases.
Step 6: Understand that the total change in entropy of the universe includes the change in entropy of the system and its surroundings.
Step 7: Conclude that in an irreversible process, the total change in entropy of the universe is positive, meaning the overall disorder increases.
