Problem 79

According to your lab partner, a 2.00-cm-thick sodium-iodide crystal absorbs all but 10% of rays from a radioactive source and a 4.00-cm piece of the same material absorbs all but 5% Is this result reasonable?

Step-by-Step Solution:
Step 1 of 3

Unit 5: Entropy  We are talking about the same entropy that you use in, say, the Gibbs free energy in chemistry courses  That being said, get the word “disorder” out of your head  Give a confusing idea of entropy  “Discarding the archaic idea of "disorder" in regard to entropy is essential. It just doesn't make scientific sense in the 21st century and its apparent convenience often is flat-out misleading. As of November 2005, fifteen first-year college texts have deleted “entropy is disorder” although a few still retain references to energy “becoming disorderly”. (This latter description is meaningless, as I shall mention here, and discuss in detail in "Disorder — A Cracked Crutch For Supporting Entropy".) Most high school texts are written by unknown people working for publishers rather than by the individuals listed on their covers. Thus, they are slow to include changes in scientific concepts and your HS text may still contain the obsolete “entropy is disorder” Clarifications:  Probability is defined in terms of an infinite number of trials o A fair coin would, by definition, land heads 50% of the time in an infinite number of trials  We consider a coin flip to be random because of the hidden variables o Exact amount of force applied at specific place, air currents  Of course doing an infinite number of flips and perfectly fair coins impossible o Near perfectly fair coins can be constructed o “While imprisoned
