In which process does the entropy of a system decrease?

In which process does the entropy of a system decrease?

Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Know that in most processes, entropy tends to increase. This is a natural tendency in thermodynamics.
Step 3: Learn about adiabatic processes. An adiabatic process is one where no heat is exchanged with the surroundings.
Step 4: In adiabatic compression, work is done on a gas, which increases its pressure and temperature.
Step 5: During this process, the gas's entropy can decrease because the work done on it organizes the particles more, reducing disorder.
Step 6: Conclude that adiabatic compression is a specific process where the entropy of the system decreases.
