Textbook Question
Chapter 8.1, Problem 3CC
WHAT IF? → If you place a teaspoon of sugar in the bottom of a glass of water, it will dissolve completely over time. Left longer, eventually the water will disappear and the sugar crystals will reappear. Explain these observations in terms of entropy.

Reflect on the concept of of entropy and relate it to life and death. How come a baby forms in the womb? Doesn't this violate the second law of thermodynamics? can we ever stop aging?
Define entropy and enthalpy. Do living cells increase entropy within themselves? Do they increase entropy in the environment?
Consider a system consisting of an egg in an incubator. The white and yolk of the egg contain proteins, carbohydrates, and lipids. If fertilized, the egg is transformed from a single cell to a complex organism. Discuss this irreversible process in terms of the entropy changes in the system, surroundings, anduniverse. Be sure that you first clearly define the system and surroundings.
