Chapter 10: Problem 2

Of the things that a car owner has to purchase routinely-gasoline, oil, antifreeze, tires, spark plugs, and so on - which are normally sold in quantized units, and which are not?

Short Answer

Expert verified
Answer: Tires and spark plugs are sold in quantized units, while gasoline, oil, and antifreeze are sold in non-quantized units.

Step by step solution

01

Analyze Gasoline

Gasoline is sold by volume, usually in gallons or liters, which means it's not a discrete unit. However, you can choose the exact amount of gasoline you want to purchase, making it non-quantized.
02

Analyze Oil

Oil can be purchased in discrete units, such as quarts or liters. However, you can also purchase oil by volume at some service stations, similar to gasoline. In this case, we will consider oil as non-quantized due to the freedom of choice in the amount desired.
03

Analyze Antifreeze

Antifreeze, like oil, is often sold in discrete units, such as gallons or liters. However, it is also possible to buy antifreeze by volume at some automotive stores. Given this, we will consider antifreeze non-quantized as well.
04

Analyze Tires

Tires cannot be sold in partial quantities, and each tire is counted as a discrete unit. Therefore, tires are quantized units.
05

Analyze Spark Plugs

Spark plugs are discrete entities and are sold as individual pieces or packs containing a set number of spark plugs. Because of this, spark plugs are quantized units. In conclusion, tires and spark plugs are quantized, while gasoline, oil, and antifreeze are non-quantized.

Radioactive strontium (Sr) tends to concentrate in the bones of people who ingest it. Why might one expect that strontium would behave like calcium (Ca) chemically and thus be preferentially bound in bone material, which is predominantly calcium in composition?
