Question
Chapter 2, Problem 85CP
Interpretation Introduction
Interpretation:
The amount of lead (in kg) that is emitted from a car travels 10000 miles in a year. The average speed of car is 25 miles/ gallon and 1 gallon contains 2.0 g of lead.
Concept Introduction:
Conversion factors are the fractions which show the conversion of one unit to another. Dimension analysis method is used with conversion factors to change the units of given values. Different units' systems like metric and U.S systems are used to represents different units of measure values and also can convert into each other with the help of dimension analysis. The equality indicates the direct relation between two units whereas conversion factors is always written as fraction in which one unit will come as numerator and other as denominator.
