Question
Consider the following processes. Which could be characterized a DECREASE in the entropy of the system? 1) The violent explosion of TNT ( a solid chemical compound) into several simple compounds, some of which are gaseous. 2) A large rock tumbles to the ground and breaks into a multitude of pieces 3) The absorption of odorous gaseous compounds by the charcoal filter in your home's entral air cleaning unit. 4) A carton of milk is left out overnite in the old and freezes in the carton. 5) The mixing of one liter of water with one liter of ethylene glyol to produce one liter of an antifreeze solution.
Explanation / Answer
Entropy is the disorderness of a system. Entropy of a system decreases as the randomness or disorderness of the decreases.
1. TNT paarticles in solid form are orderly arranged whereas in gaseous form they are more disorder. So, the entropy of the system increases.
2. The large rock more ordered than the pieces. So, the entropy of the system increases.
3. The absorbed gases are more ordered than free gases. So, the entropy of the system decreases.
4.The particles in fFreezing milk is more ordered than normal milk, So, the entropy of the system decreases.
5. Entropy decreases when mixing the solutions.
