Dimensional Analysis is a way of doing numerical "book-keeping"
when converting quantities or performing calculations.
• When converting quantities from one unit to another,
conversion factors are used.
Solving with Dimensional Analysis and Multiple Units:
If I am in Canada where the price of gas is $1.022 USD·L1, how
much will it cost me to fill up my gas tank if I travelled 125 km?
• Let's also assume that my car gets
an average of 30.0 miles/gallon.
You are asked to calibrate a 25 mL volumetric pipet. You determine that the temperature of your distilled water is exactly 24.5 degrees Celsius. You carefully determined the mass of a clean dry beaker and found that it was 57.5513 g. You pulled water up to the mark and transferred this to the beaker and found that the new mass was 82.9344 g. What is the actual volume of the pipet? The density of water at 24.5 degrees Celsius is 0.997983 g/mL.

- After sitting on a shelf for a while, a can of soda at a room temperature (69°F) is placed inside a refrigerator and slowly cools. The temperature of the refrigerator is 37°F. Newton's Law of Cooling explains that the temperature of the can of soda will decrease proportionally to the difference between the temperature of the can of soda and the temperature of the refrigerator, as given by the formula below: T = Ta + (To – Ta)e¬kt the temperature surrounding the object To = the initial temperature of the object t = the time in minutes the temperature of the object after t minutes k = decay constant T The can of soda reaches the temperature of 54°F after 40 minutes.
