Problem SolVing and Dimensional Analysis Problem: Suppose you have to pick up doughnuts on your way to school. You need 2 dozen for the class, but you stop at a store that only sells by the doughnut. How many do you get? Problem: The cost of a jar of pickles is $2.06. You have S10.00. How many jars of pickles can you pick up? Both problems involve conversions. Conversion factor- a ratio of the two parts of statement that relates the two units (= 1) Ex. 2.85 cm ? in Ex. 1.12 in =? cm

Chemistry: Matter and Measurements Objectives: - To learn how dimensional analysis can be used to solve various types of problems - To learn the three temperature scales - To learn to convert from one scale to another; continue to develop problem solving skills Problem Solving and Dimensional Analysis Problem: Suppose you have to pick up doughnuts on your way to school. You need 2 dozen for the class, but you stop at a store that only sells by the doughnut. How many do you get? Problem: The cost of a jar of pickles is $2.06. You have $10.00. How many jars of piekles can you pick up? Both problems involve conversions. Conversion factor- a ratio of the two parts of statement that relates the two units (= I) Ex. 2.85 cm =? in Ex. 1.12 in = ? cm Converting from one step to another Step 1 To convert from one unit to another, use the equivalence statement that relates the two units. The conversion factor needed is a ratio of the two parts of the equivalence statement. Step 2 Choose the appropriate factor by looking at the direction of the required change (Make sure the unwanted units cancel). Step 3 Multiple the quantity to be converted by the conversion factor give the quantity with the desired units,
