Chapter 3, Problem 119E

Examine the data for the maximum and minimum average temperature of San Francisco and Sacramento in the summer and in the winter.

San Francisco (Coastal City)

January		August
High	Low	High	Low
$57.4{}^{\circ }\text{F}$	$43.8{}^{\circ }\text{F}$	$64.4{}^{\circ }\text{F}$	$54.5{}^{\circ }\text{F}$

Sacramento (Inland City)

January		August
High	Low	High	Low
$53.2{}^{\circ }\text{F}$	$37.7{}^{\circ }\text{F}$	$91.5{}^{\circ }\text{F}$	$57.7{}^{\circ }\text{F}$

a. Notice the difference between the August high in San Francisco and Sacramento. Why is it much hotter in the summer in Sacramento?

b. Notice the difference between the January low in San Francisco and Sacramento. How might the heat capacity of the ocean contribute to this difference?
