e. A banquet table set for dinner, a banquet table during dinner, a banquet table immediately after dinner.

8.7 Pick the example with the highest entropy from each of the following sets. Explain your answers. a. Solid ice, liquid water, or steam b. Leaves on a tree, fallen leaves blown about on the ground, fallen leaves raked and placed in a basket c. A stack of sheets of paper, a wastebasket containing sheets of paper, a wastebasket containing torn and crum- pled sheets of paper

Answer 1

Entropy is a quantity which determines the Randomness in the Order. More random the behaviour, more will be the Entropy.

1. Out of Ice, Water and Steam, Stear which is in gaseous form will have more random motion of the molecules which constitute it. Solids will have a tightly packed structure while water will have less tightly packed structure. But molecules in steams will be randomly spread in air.
Hrence Steam has highest Entropy.

2. Fallen leaves blown on the ground will be spread in ground in a random manner. While leaves on tree or leaves assembled in the basket will be orderly arranged.
Hence Fallen leaves blown on the ground will have highest Entropy.

3. Waste Basket contating Torn Sheets of paper will be most randomly arranged and hence will have highest Entropy.
